Every gamer that ever played knows the unique agony that accompanies falling at the final hurdle. Whether that means popping your clogs within sight of a checkpoint or being brutalised by a near-dead boss monster - gamers know that no defeat hurts worse than that which was so very nearly a victory. At times, managing your hype for an upcoming game can feel little 'game-like' in and of itself. And just like a game, the prospective title that tests our patience, only to disappear mere weeks from release always stings that much more.

Today's big list of stuff looks at ten games that made it all the way to within spitting distance of release, only for outside factors to quash their drop. Some are sure to inspire a profound sense of longing, while others remain fairly unknown - some deservedly, others less so. These then, are ten titles we oh-so nearly came to play. Enjoy.

What? - A massively multiplayer RTS title set within the Dune universe. Players would have chosen between three dynastic groups - the soldiers, traders or mercenaries - and proceeded to carve out their own small empire on Arrakis. Interestingly, the game wasn't to be helmed by Westwood Studios (they of Dune 2 fame), but rather by their predecessors at Cryo Interactive, i.e. the same team that produced the Dune adventure game.

When? - Work on the project was shut down during the title's alpha testing phase, in which a functioning build of the game is put through its paces. Hardly the finished product, but with the vast majority of its workload now behind it

Why? - Developer Cryo Interactive entered bankruptcy in July of 2002. The studio had previously bet big on the success of its other Dune-related property - a third-person action title named Frank Herbert's Dune. Sadly, the game flopped, ultimately costing the studio the opportunity to complete its more ambitious MMO cousin.

What? - A third-person action-RPG similar in many respects to the Mass Effect franchise. In addition, the game was also said to feature a heavy emphasis on base building, forcing players to scout out an infested structure in order to toughen up their stronghold. Think of it as a quasi-survival sim, akin to the central predicament of the second Alien film. Oh, and just to add insult to injury, the game was also being developed by genre stalwarts Obsidian, creators of Fallout: New Vegas, Pillars of Eternity and South Park: The Stick of Truth. Yeah, it was probably going to be good…

When? - Obsidian's Feargus Urquhart has stated that Crucible was in such an advanced state that it almost appeared ready to release. His colleague Chris Avellone took a slightly less advanced view of the project, arguing that the title only appeared so close to completion because of special efforts made to debut a demo. In either case, Crucible was undoubtedly well into development by the time Sega pulled the plug.

Why? - Sega decided to de-clutter its portfolio -meaning either that the game was costing too much to maintain value, or that the publisher was worried about overexposure. Whatever the reason, Crucible ended up canned. A shoddy stroke of luck for any developer, but one made infinitely more aggravating by the titles Sega chose to press ahead with. 2010's AVP proved to be a thoroughly average adventure, whilst the less said about Aliens: Colonial Marines, the better. Bad call Sega.

What? - An enormous team-based multiplayer title set within the Star Wars universe. Unannounced and unreleased, details on the game remain sketchy, however a small number of interesting titbits have emerged. With Pandemic Studios choosing to move on, development duties passed to Free Radical Design - home to the outrageously entertaining TimeSplitters series. Leaked pre-alpha footage indicates that the studio was working on a fully-fledged storyline, disparate elements of which may have been repackaged into the PSP exclusive Elite Squadron.

When? - According to Free Radical founder Steve Ellis, Battlefront 3 was 99% complete when LucasArts jettisoned the project. An anonymous source would later claim that the figure actually stood at around 75%, prompting Ellis to publically deny the allegation.

Why? - Prior to its acquisition and subsequent shutdown by Disney, LucasArts had commenced upon a widespread company shakeup. As Ellis and co-founder David Doak tell it, Free Radical went from being told to 'think bigger', to cutting back every conceivable cost. Doak would even go so far as to name the project's second set of executives as "psychopaths", intent on the franchise's failure. According to Ellis, the official reason given for the game's cancellation was a lack of necessary marketing funds. The anonymous source meanwhile claimed that the studio had repeatedly missed deadlines and was even redistributing assets onto its other projects.

What? - An ambitious MMORPG project announced back in 2002. Developed by Level-5 (of Dark Cloud and Ni No Kuni fame) True Fantasy Live Online was designed to take advantage of a then-fledgling Xbox Live. Servers would have held around 3000 players apiece, with fully-integrated voice chat between parties.

When? - Level-5 President Akihiro Hino stated that "the world of TFLO was already complete" at the time of the game's shock cancellation. The title was scheduled to enter Beta testing soon thereafter, with a speculative Japanese release date of autumn, 2004.

Why? - Despite its advanced state of completion, TFLO failed to live up to Microsoft's standards. Several overly ambitious features, including widespread voice chat proved tricky to accomplish, fraying relations between the developer and its publisher. Given that the game had already received plenty of positive buzz, TFLO might well have transformed the fortunes of the Xbox brand in Japan. As it is, the game would wind up as a painful reminder of MS's failure to crack that market.

What? - A controversial 4-player beat-em-up title. Thrill Kill combined Mortal Kombat with Manhunt, boasting blood and guts gameplay alongside fetishistic visuals.

When? - Thrill Kill was completed and ready to ship.

Why? Having acquired the property as part of its takeover of the Virgin US label, EA opted to cancel Thrill Kill's release. It was felt that the game's deliberately controversial nature jarred with that of the EA brand. In addition, the company also forbid the title to be sold on to any other publisher, effectively killing off the game. Fortunately for fans, the finished title was soon leaked online, making it one of the more readily available games of that sort. Activision would later utilise the Thrill Kill's engine to create Wu-Tang: Shaolin Style, X-Men: Mutant Academy and its sequel Mutant Academy 2.

What? - Remember the Gizmondo - Tiger Telematics' failed attempt to crack the handheld market? Colors was to be that machine's first 'killer app' - a gang-based third-person shooter with GPS player location. Strangely, the game also allowed players to indulge in seedy prison sex (participants would receive early release)… I just can't imagine why it didn't succeed.

When? - Leaked copies of the game suggest that Colors was all-but complete at the time of its cancellation.

Why? - The Gizmondo became the worst-selling handheld of all time, bankrupting Tiger Telematics and putting and immediate stop to all games then in development.

What? - A tactical action game boasting numerous RPG elements. Black9 took its inspiration from the Deus Ex series, positing a cyberpunk world divided between warring cartels. Former Taldren Inc. developer Erin Hoffman argued that the game was so very "special", that it may even have changed the lives of a small portion of its players. High praise indeed then.

When? - Hoffman stated that the game was around 85% complete at the time of its cancellation.

Why? - According to several parties involved in the Black9 project, publisher Majesco proved to be an overly demanding and highly unprofessional partner. Having already released two commercial flops - including the critically acclaimed Pyschonauts and the supposed franchise starter Advent Rising - Majesco was beginning to feel the pinch. They in turn put to squeeze onto Taldren, demanding 'crunch time' level working hours throughout the entire life of the project. Hoffman claims that the studio rallied to hit these targets but was still denied promised funding. Later, - again according to Hoffman - two programmers were surreptitiously 'lent' to the project so as to steal the game's source code. This was allegedly done in order turn the game - a property wholly owned by Taldren Inc. - over to a brand new developer. With the near-complete title in its possession, Majesco would then attempt to lure key personnel away from the studio, at which point the team chose to shut its doors rather than to let Majesco win. Later, many of the Majesco executives involved in the Black9 botch were ousted by the company's shareholders, with Hoffman herself describing the modern publisher as 'a very different company'.

What? - A realistic, tactical FPS based on the Second Battle of Fallujah, aka the bloodiest battle of the Iraq war. Developer Atomic Games intended to create what might best be described as a 'survival-terror' game, in which the player never feels wholly safe from attack. Long stretches of agonising tension would be broken up by moments of breathless, violent confrontation, echoing the real-life experiences of many soldiers involved in the battle.

When? - An 'insider source' speaking to IGN claimed that work on the game was completed sometime in late 2009/ early 2010.

Why? - Given the recent nature of the events depicted, many commentators found the game to be in poor taste. When word of this controversy reached publisher Konami the company responded by dropping the project entirely. Atomic Games was subsequently unable to secure a new publisher and later released a large number of its staff. However, studio president Peter Tamte remains committed to the project, confirming that 6 Days was still in development as recently as 2012. The game's current status is unknown.

What? - After 16 years of annual releases, EA opted to retire its NBA franchise in 2011. However, just two years later the brand was back.

When? - EA's big comeback made it to the figurative post-season before being abruptly cancelled just weeks ahead of its proposed release.

Why? - EA exec Andrew Wilson stated that the game was simply not ready enough to hit its scheduled release date. Instead the company would take another year to develop a truly "great" experience. NBA Live 14 went on to receive some of the worst review scores in series history. Ouch.

What? - A sprawling space-based FPS title. Human Head's vision for the game featured an amnesiac U.S. Marshall named Killian Samuels - abducted from the earth and now plying his trade as a galactic bounty hunter.

When? - Former Human Head developer Jason Blair described the title as a 'full game', denying claims made by publisher Bethesda that Prey 2 was merely "a demo" at the time of its cancellation. Project Director Chris Rhinehart has also stated that the title was close to reaching its alpha stage, with most of the game's major elements already in place.

Why? - How long have you got? The saga of Prey 2 is a sad, strange and complicated one, so let's just stick to Human Head's involvement. Having developed the first game in the series, HH teamed up with Bethesda Softworks to publish its ambitious sequel. However, by 2013 the developer had been completely removed from the project, with Bethesda citing an overall lack of quality for the shuffle. For its part, the scorned studio remained proud of its efforts on the game, with many senior devs pointing to internal politics as reason for the changeover. Prey 2 was officially confirmed cancelled in October, 2014.

What do Hollywood blockbusters have in common with the number 35 bus? Why, that's easy - you wait an absolute age for one, only for two to turn up at once. Take Armageddon for instance - aka the movie in which Steve Buscemi was exposed to the harsh vacuum of space... no wait, I'm now being told that he looked like that already. Sorry Steve… Simply put, Armageddon was all about asteroids crashing into the earth. So, a lot like that other movie from 1998 - Deep Impact. Coincidence? Guess again chums, because these two twins were far from unique. Consider 2014's Hercules vs The Legend of Hercules or Iron Eagle vs Top Gun. How about Olympus Has Fallen vs White House Down? The list goes on.

Indeed, cinematic history is packed tight with examples of oddly analogous movies. But what about gaming? Does the interactive medium boast its fair share of twinned features too? Well let's bloody well hope so - It's going to be an awfully short feature otherwise…

Criteria check - To avoid unnecessary confusion over release dates I'm only going to including US release dates.

Superheroes and sandbox games go together like Gwen Stacy and gravity. When a major player opts to drop one, you'd better believe it's going to be memorable. One part urban strife, six parts spandex - a winning combo by any estimation. Sadly, precious few of these titles actually exist - something to do with the inherent difficulty of coding up 'two' titles at once. A solid superhero game and a sprawling cityscape? One alone should be enough to drive most developers to drink.

Then there's Infamous and Prototype, two games that dared to make good on the promise of that premise. Both titles starred reluctant everymen receiving outrageous new abilities. From there players were encouraged to either go good or be bad - to fight crime or to fuel it. Though broadly similar, both efforts remained different enough to warrant a double dip. That is until they made the mistake of launching some two weeks apart. Perhaps it's only proper that these two superheroes duked it out directly, though it couldn't have done either game's sales a world of good.

I'll wager there were more groans than at a disappointing orgy the day these two titles first caught wind of one another. Just think of it - one second you're riding high, confident of a unique concept, the next you're reading up on some accidental doppelganger. I suppose it's faintly absurd that two titles based around psychic powers couldn't perceive the other one coming. So much for their vaunted foresight...

With scarcely 10 weeks between releases, Psi-Ops and Second Sight effectively trod on one another's toes. Both had attempted to inject some much-needed variety into the veritable scrum of 3rd person shooters. Sadly, their too-close proximity would quickly put paid to that - making both efforts seem now newly unoriginal.

Attempting to differentiate your game is a tough old ask even at the best of times. Fans and critics alike essentially crave a good frame of reference, be it a basic genre tag or a more specific comparison. "It's a bit like this", or "a whole lot of that" can express in mere seconds what might otherwise take aeons to describe. Now imagine that you're marketing a driving title. Real cars on realistic tracks, all bombing it around at ridiculous speeds. Fun yes, though not exactly varied.

Wisely, both Blur and Split/Second attempted to surmount these issues through the use of nifty gimmicks. The former went all RL Mario Kart - boasting 'car-based combat for grownups', while the latter prized raceway destruction on an enormous scale. Good start. Now if only they hadn't released one week apart and stolen each other's thunder. Every last forking bit of it.

Talk about a pair of heavy hitters. In the red corner, one hotly anticipated sequel to the biggest MMO going. And in the blue, all the might of the Warcraft franchise brought to bear on a burgeoning genre. If ever there was a time to stop WoW from achieving its world domination, then this surely was it. Killed in its infancy, like some sort of mad sci-fi plot to assassinate the Baby Hitler.

The biggest name in MMOs vs the genre's heir apparent. Going toe to toe, with barely two weeks between them. You might say that the stakes were even higher than a spectator at a Columbian forest fire, and you’d be right. Both games were good - damn good in fact, each one deserving its fair share of the MMO userbase. The fact that Warcraft was able to not only best its rival in 'single combat', but also claim the vast share of subscribers only adds to considerable legend.

Mooching off the movies is a well-established pattern amongst video game developers. Just look at the likes of Contra, a game that disguised its obvious nods/ bloody-minded plagiarism about as well as a knock-off Chinese Disneyland. Oftentimes, tracing the root of these trends is easy enough. After all, Contra appeared just 8 months later than Jim Cameron's Aliens. Coincidence? I think not.

Then there are games like Arabian Magic and Arabian Fight, a pair of solid arcade brawlers bearing eerily similar settings. So, where on earth did their developers get the idea to look to the Middle East - a largely untapped creative avenue, outside of the modern military shooter? Why, that's simple, you say - Disney's Aladdin appeared in the very same year! Except of course that Aladdin hit cinemas after both titles had already debuted. So, either someone smelled money in those early trailers, or three independent studios (including Disney) all decided 1992 was to be the year of Turkish trousers.

Not a release date this time, but a shared announcement phase. Both Elite: Dangerous and Star Citizen opted to take their projects public within just seven weeks of one another. So far, so standard - or so you may think - but what exactly do these intrepid explorers have in common? Well for starters, both games have taken a long dormant genre, i.e. the spaceflight sim and recreated it in MMO form. On top of that, both titles were successfully kickstarted into being, all whilst handily exceeding their original funding targets.

Then there are the creative minds involved. Star Citizen's Chris Roberts created the much-loved Wing Commander series, while Elite's David Braben is practically responsible for the entire genre. So, to recap - that's two giants of the genre, two big-time comebacks and two parallel crowd funding campaigns all unveiled within two months of one another. Too sweet.

Much like the aforementioned Blur and Split/Second, both of these titles bet big on a flashy new gimmick. Call it 'car driving for the social networking age'. Sadly, neither title could quite outdistance the other, running so close together as to create a veritable car crash of confused gamers. In addition, both titles suffered from various network-related glitches, issues that would eventually contribute to a lukewarm critical appraisal.

Despite all this, both games would go on to sell some 2 million copies apiece, not bad at all, especially when you consider that Drive Club only appeared on the PlayStation 4 format.

Two major players both launching within a month of each other? Sounds like franchise suicide. After all, somebody's got to lose. "I know - you'll be Betamax and I'll be VHS. No no no, you be HD DVD and I'll be Blu Ray". At least, that's how you might expect events to unravel. In the case of Unreal Tournament vs. Quake III Arena, neither party saw fit to suffer such a mortal injury. Instead, both games would go on to receive a slew of successful sequels.

It's a bit like that one movie Twins, except in this instance both men grew up to be the Arnold Schwarzanegger variety. So, it's actually a lot like The 6th Day, in which Arnie grows himself a clone. No wait, it's might be more like Junior, wherein the Austrian Oak births himself an Arnie baby. Wait… what was I talking about? Oh right, madcap multiplayer shooters. I suppose it's rather ironic that of all the entries on this list, the genre with the most gun happy patrons should agree to live and let live. I guess this town really is big enough for the both of us.

Now, here's an entry you couldn’t have seen coming… I'll bet it really snuck up on you… You might even say that it quietly approached in the dead of night before violently opening your throat. No, wait - that last one doesn't work. But enough hilarity for one moment, let's get back to business. What is it exactly that makes these two titles - set some 500-odd years apart - so similar as to be counted as 'twin releases'?

Well, if we're talking broad strokes here, then plenty. Both Tenchu and Metal Gear Solid marked a brave new foray into the world of 3D stealth-em-ups. Sure, the latter title may have had a solid 2D pedigree behind it, but the genre itself had never really gained any mainstream attention. These are the games that helped change that, debuting within a mere two months of one another. Moreover, the equally important Thief series also launched at around this time, solidifying a whole new genre in the space of around 12 weeks. Not bad.

It's not every day that an uber violent homage to the 1980s appears. Well, unless that day just so happened to occur within the month of October, 2012. Released within two weeks of one another, Retro City Rampage and Hotline Miami might well have contended for the crown of most 'pixellated blood bath'. Instead Hotline met with enthusiastic reviews, whilst Rampage could only muster up a string of middling appraisals.

A more fitting scrap might've seen the two titles donning animal masks, nabbing a pair of DeLoreans and jousting it out on the sunset strip. A man can dream, cant he? *sigh*
