You feel that in the air? The constant buzzing of press releases and hype trailers? It's E3 season, and that means it's time to get excited once again about the future of video games. Usually, the E3 lifecycle works like this: watch a trailer and some gameplay footage for a hot new game at E3, get really excited about it, wait about a year or two, then finally walk to your local store and pick up a copy of the game.

Sometimes, though, games get stuck at the 'waiting' step and never find a way to get out. Time continues to march on, E3s come and go, and these games either disappear into the aether, or get cancelled outright, leaving behind a video or two and brief demo a handful of people actually got to try. So let's gather ‘round, reminisce on promises left unfulfilled, and pour one out for these E3 vaporware games.

When the Wii was originally unveiled at E3 2006, Nintendo also showcased an array of games that would make a case for its then-unheard-of motion controls. Look at all these beautiful people flailing the Wii Remote around as they wield a virtual sword, baseball bat, or hammer! And while demoed games like Red Steel, Wii Sports, and The Legend of Zelda: Twilight Princess saw the light of day, it was Project H.A.M.M.E.R. that was doomed to get the axe.

In Project H.A.M.M.E.R., you would play as a burly dude covered in power armor, and your objective was to swing around a massive sledgehammer, obliterating every enemy and object in sight. That seems to be about as far as the dev team got, as the game was considered "paused" as of E3 2007. While not officially cancelled by Nintendo, it's been nearly nine years since its initial unveiling, so make of that what you will.

Some console names are a bit strange (seriously Nintendo, the Wii?), while others are a bit more obvious, perfectly encapsulating what the machine is and does (like the PlayStation). But no name is more perfect than The Phantom, a console developed by Infinium labs that, other than brief showing at E3 2004, never saw the light of day.

The Phantom was a console developed by Infinium Labs (rebranded as Phantom Entertainment in 2006). Revealed in 2003 then arriving at E3 in 2004, the idea behind it was, at the very least, ambitious. For under $399, The Phantom was to be a PC that hooked up to your TV like a console, letting you download and install games directly to the device via the internet. It was essentially a Steam Machine before Steam was even a thing, but release dates came and went as the machine's release ended up pushed beyond 2005, finally removed from Phantom Entertainment's website in 2006. Perhaps the world just wasn't quite ready for a living room PC solution, but at least there's a silver lining to this story: Phantom Entertainment still exists, and - a couch-based keyboard originally designed for the The Phantom console.

Exclusives are important for any console manufacturer. Each box essentially does the same thing, so you have to give people a reason to buy your machine over the competition's. So when Sony announced in 2007 that a game from the studio behind Grand Theft Auto was coming exclusively to PlayStation, it was perceived as a big get for the company that sat firmly in second place.

It's unfortunate, then, that the only official image we've seen of the game since its E3 unveiling was the logo. A few screenshots have leaked out since then, and publisher Take-Two still claims that the game is in development. Rockstar Games is known for taking its sweet time developing games, but eight years on a single game is a bit much.

The 21st century hasn't exactly been kind to LucasArts. For every Knights of the Old Republic, there was a Star Wars Kinect; for every Mercenaries, there was a Fracture. It wasn't exactly a surprise when LucasArts effectively ceased operations in 2013 following Disney's acquisition of basically everything George Lucas owned. But it was still a shame - especially because it meant cancelling the one project that could have put LucasArts back on the map: Star Wars 1313.

Starring a young Boba Fett, Star Wars 1313 would have followed the bounty hunter's first adventures, and made it out to be a third-person shooter filled with heavily-scripted set-pieces, similar to Uncharted. Except, y'know, it's Star Wars. While the demo looked promising, 1313 was officially canned a year later, as LucasArts laid off the majority of its staff.

Some games are lucky enough to escape their vaporware fate, and there's probably no greater turnaround story than Prey, that somehow actually turned out alright considering the circumstances. Unfortunately, its sequel didn't end up so lucky.

While a sequel was reportedly in development shortly after the first game's release in 2006, it wasn't officially unveiled until 2011. Taking place after the events of the first game, Prey 2 would have followed the adventures of US Marshal Killian Samuels, a single human living among an array of alien races, hunting bounties and earning cash to survive. Prey 2 made a showing at E3 that year, but shortly after, rumors began to swirl about its cancellation. Bethesda continued to deny rumors until 2014, when Bethesda VP Pete Hines confirmed that development on the title had ceased.

So Nintendo struck paydirt with the Wii, and games like Wii Fit and Wii Sports flourished with an audience who would have never thought to pick up a gaming console in their lives. In an effort to keep that gravy train rolling, Nintendo wanted to create a controller that everyone could use, a controller so simple, all you have to do is put your finger in it and sit there. Enter the Vitality Sensor.

In an ideal world, the Vitality Sensor would have gathered the player's biometric data (namely, their pulse) and the game would then take that data and react accordingly. But despite an initial announcement by Nintendo CEO Satoru Iwata at E3 2009, the device essentially disappeared without a trace. It wasn't until 2013 that Iwata confirmed why this strange peripheral never got released: turns out, it only worked for . It doesn't sound like that big of a gap, but when ten percent of the people who buy your product are returning it because they think it doesn't work, it's probably best to shelve it.

Peter Molyneux is basically the Willy Wonka of game design - except Molyneux's Fizzy Lifting Drinks don't do much more than taste like an off-brand Sprite and give you a slight caffeine buzz. Not that he makes bad games; it's just that they end up kind of pedestrian in comparison to the pie-in-the-sky promises that he makes leading up to their release. And there's perhaps no greater example than Molyneux's ability to over-promise and under-deliver than Project Milo.

The idea (as these things tend to go) looked promising, as you interacted with a virtual young boy with voice and hand gestures via Kinect, and the boy would react to your statements and change over time. It all sounded a bit too good to be true, especially considering , despite Molyneux's insistence to the contrary. Considering Molyneux's departure from Microsoft in 2012, it's doubtful this project will be completed.

You'd be forgiven if you don't remember the original Phantom Dust on the Xbox. Even though it was developed by Microsoft Japan, it's still pretty niche, combining third-person action, card-collecting, and multiplayer arena battles. Microsoft's been on a rebooting kick lately, taking old properties that the publisher owns and getting other studios to remake them for Xbox One. Phantom Dust was the latest to supposedly get the treatment, complete with an E3 2014 trailer.

But within a year of its announcement, the studio behind the remake , leaving the ultimate future of Phantom Dust in question. Microsoft has stated that they are committed to the title and that development still continues, but it's probably going to be another couple of years before we ever see anything about this strange hybrid again. I suppose getting shut down quickly is better than getting strung along for years, but still - that was fast.

Las Vegas, that strip of hedonism and hubris out in the middle of the desert, has never really been immortalized in video games (though Fallout: New Vegas gets it pretty close). There are casino games, sure, but there's never been been a game that fully encapsulates the celebrity DJ/bottle service/$7.99 all-you-can-eat buffet experience that Las Vegas is really known for. And thanks to the cancellation of This Is Vegas, we're going to have to wait even longer.

First hinted at in 2006, the splendor of This Is Vegas wasn't fully revealed until 2008, and was scheduled for release later that year. Unfortunately, thanks to publisher Midway's own personal financial woes (many of them likely brought on by This Is Vegas' ballooning costs, as the publisher reportedly spent Keep the Vegas dream alive.

Here it is: the White Whale of vaporware. Blizzard is known for only releasing games when they're "done", which of course means they take years longer to make than most, and the studio isn't afraid to shelve something if they don't think it's worth continuing - even if that means cancelling a game after years of development. StarCraft: Ghost would have put players in the role of the titular sniper as she sneaks her way through various sci-fi environments, completing objectives, and shooting Zerg in the face.

Unfortunately, development didn't go as smoothly as you'd expect. Originally planned for a 2003 release, Ghost underwent numerous delays, and even changed hands from developer Nihilistic to Swingin' Ape Studios. It was then relaunched at E3 2005 and slated for a release in 2006 - which came and went, and Ghost was still a no-show. Around that time, a little game you've probably never heard of called World of Warcraft released, and Blizzard decided to pour resources into its new MMO rather than continue working on a stealth-based PS2/Xbox game, so it put Ghost on indefinite hold. If you're still holding out hope, don't: Blizzard CEO Mike Morhaime finally put a bullet in this one, confirming its cancellation in 2014.

Nothing to see here. Move along.

Game trailers are an art form in and of themselves. With only 180 seconds or less to impress their audience, they need to tell an immediately arresting story that gives a snapshot of what an hours-long game will make you feel. One way to tie it all together is with a recognizable piece of licensed music, a familiar, melodic thread to guide you to the highlights of this virtual world.

E3 is gaming's trailer season, and you can bet that you'll be seeing plenty of trailers using licensed music to promote the many . With that in mind, we wanted to look back the trailers that were made more distinctive, more memorable, and (most importantly) more effective because they chose to revolve around familiar songs. Hey, all you E3 2015 trailer-smiths: these are the ones to beat.

Not all pulse-pounding rock songs are created equal. While banking on the power of screaming lyrics and throbbing rhythm usually gets a game some attention, about a million other trailers are doing the exact same thing. To be heard over all that noise, a trailer's musical accompaniment has to be distinguishable from generic beats and connected to the game in a way that makes the two feel inseparable. That's what folksy thrasher song 'Beast of America' does for the trailer of the same name.

It's difficult to envision this trailer with any other song, since the game and the tune seem tailor-made for each other. You have rustic humming and drumming at the beginning that drips with Americana. You have the obvious nods to a broken American dystopia that's everywhere in BioShock Infinite. You have vicious vocals and guitar riffs that highlight the violent, angry, and enormous visuals that fill the trailer. And you have a unique sound that stands out in your mind and makes the game do the same. Now you can't think of either the song or game without the other, which is exactly the point.

"What do you want, Michael?" asks a psychiatrist as a drum machine begins marching and keyboard strains slowly lift in the background. Michael is conflicted. He has the dream; the big house, the family, the money. But he also has nothing; his family hates him, and his days are filled with a crushing sense of self-loathing and worthlessness. As Michael begins to question what he really wants, Queen's 'Radio Ga Ga' forms the backdrop for one man's quest for meaning in a town full of fleeting opportunities to find it, and I honestly can't think of a better fit for this spectacular, explosive trailer.

The lyrics are a perfect metaphor for Michael's existential plight - a grasp at nostalgia for days gone by, when listening to the radio was something that mattered, not just 'some background noise'. Michael is a man attempting to regain the feeling of the glory days of his youth, when a big score was around every corner, but finds nothing beyond the regrets that come with mid-life crisis. Even the melody evokes strains of melancholy in its immensely danceable beat, punctuated by scenes showing exactly how Michael's life is falling apart around him. Rockstar is good at a lot of things, but ever since Grand Theft Auto: Vice City, it's been an expert at creating the perfect soundtrack, and Michael's trailer is its ultimate masterwork.

The most memorable trailers can strike a chord with people who have no intention of playing video games in general, let alone the one that's being advertised. And juxtaposing soft, melancholy piano melodies with Marcus Fenix's alleyway encounter against the Locust hordes creates the kind of attention-demanding scene that can enrapture anyone. You've got to appreciate just how big of a gamble it was for Microsoft and Epic to advertise their new red-blooded, M-rated shooter - packed with guns-blazing violence and chainsaw bayonets - by giving a brief, perfectly-scored glimpse into the forlorn desolation of the post-Emergence Day apocalypse. That gamble paid off, big time.

It's all anchored to Gary Jules' somber cover of 'Mad World', which puts the sadness of Tears for Fears' original lyrics into focus. The song was certainly memorable in Donnie Darko, but the Gears of War launch trailer makes it absolutely unforgettable for an entire generation of gamers. I still get chills when Jules croons the chorus just as Marcus is desperately firing on a gargantuan Locust he can't possibly defeat.

Ok, yes, it's dubstep. Go ahead and get all the hate for that particular overused musical style out of your system, because Nero's 'Doomsday' is the perfect backdrop for the delightfully bombastic, cheerfully ridonkulous action of . Really, what other kind of tune are you going to put behind a trailer that tells you to "Get ready to joy puke your face off"? Jazz? Stop.

Borderlands is a game that rejoices in its absurdity, revels in its violence, and reminds us that shooting things is a really, really fun thing to do. Borderlands 2 cranks up the volume in every way possible. The 87 bazillion guns get bazillionder, there are more skills (for the payment of bigger bills), and it’s 1,000 degrees hotter. Mostly, though, it's a colorful departure from typical gritty shooters and it simply wants you to have a good time doing violence on Pandora. The thumping beat of 'Doomsday' accentuates the quick shots of Borderlands 2's gameplay, accelerating your pulse until the volume plummets and Handsome Jack makes his appearance. We're gonna need a lot of guns...and 96.5% more wub wub.

When it comes to Prince of Persia trailers, Ubisoft has a format they like to stick to: footage of the Prince beating up enemies and using time-travel acrobatics, while a Moviefone narrator talks very seriously about destiny. The point is to make the Prince look like a proper action hero, but it pushes a simplistic view of who he really is. That's what makes the E3 trailer for the 2008 Prince of Persia reboot so interesting: it presents the Prince in a more thoughtful light, and the accompanying song - Sigur Ros' dreamy ballad 'Sæglópur' - shows just how different this Prince of Persia is meant to be.

Avoiding the quick transitions between fight scenes that you might expect to see, Sæglópur's gentle rhythm slows the trailer down, honing in on the way the characters move together and the world they're moving through. It also strengthens the mystical nature of their combat, and it feels like the music is given form through the Prince and Elika's colorful explosions of magic. The crescendo of the song comes just as Elika turns their battlefield into a lush, sunlit landscape, showing this is what the game is meant to be about: these two rebuilding the world. This new Prince feels different from his generically impressive former self, because Sæglópur has given him a different tone. One that sticks with you well after the trailer is over.

This trailer is all fire and rage and hate; a descent into madness stretched across five minutes that feel like an eternity. Leading the charge is its title track 'Nuclear' by English prog rocker Mike Oldfield, which I wrongly assumed had been written specifically for the trailer. This song perfectly encapsulates what's going on with Big Boss' character, while also invoking the overall tone of this game. The lines 'I'm nuclear / I'm wild / I'm breaking up inside' sum up the game's protagonist in a nutshell: a broken soldier whose life has been going to hell ever since the events of Metal Gear Solid 3.

Layered on top of these lyrics are images of violence that are extreme even by Metal Gear standards. This creates a striking contrast between and rest of the series. Sure, Snake's exploits have explored torture and other dark themes, but they've always been tempered with the levity of giant robots and people with superpowers. None of that is on display here. Instead it's all stabbing and torture and dismemberment, which together set a powerful (if not grisly) expectation for how this adventure will play out.

A lot of the trailers on this list take a solemn, serious tone, amplified by a poignant piece of music. And when it comes to melancholic drama, there's really no topping the original Dead Island trailer. So I was delighted to see the reveal go in the complete opposite direction, with its bright, light-hearted, and comically chaotic tone. Ignoring the fact that this sequel takes place in California - which, last I checked, is not an island - this trailer perfectly captures the fun side of a sunny zombie apocalypse.

Pigeon John's 'The Bomb' is irresistibly catchy, making you want to clap along to the poppy rhythm which, like a zombie's diet, is organ-centric. And John's jovial, self-congratulatory chorus of "I'm the bomb and I'm 'bout to blow up" perfectly matches the vanity of this tanned, teeth-whitened male model even as he slowly decomposes, as well as the impending explosion of undead pandemonium that's erupting right behind him. Even with the gazillion other trailers shown off during E3 2014, the song - and the accompanying scene of morning cardio gone to hell - kept running through my mind all week long.

If you're a fan of 19th century sea shanties, you've probably heard doesn't match that description at all, and the rendition of 'Drunken Sailor' used in its E3 debut trailer (changed to 'Drunken Whaler' to fit the game's environment better) becomes a whole lot darker to match.

The visuals in this trailer gracefully lay out the basics of Dishonored: where you'll go, who you'll run into, and the violent methods you have to dispose of most of them. However, it's the song that really lodges the whole thing in your brain. The music alternates between unsettling wisps of sound and pounding industrial cacophony; add that to a creepy child singing 'slice his throat with a rusty cleaver', and the music drives home that there's something deeply wrong with this place and everything you're seeing in it. Where the images could easily have been a dull catalog of whos and whats, 'Drunken Whaler' brings Dunwall to disturbing life, and makes you want to experience its horrors for yourself.
