From GamesReviews:
"Metal Gear Rising Revengeance sent up some red flags when it was announced; it didnt have Snake as a playable character, it wasnt part of the main Metal Gear storyline, and it was an action game with very little of Metal Gears genre-defining stealth gameplay. However it was developed by Platinum Games, the studio behind Bayonetta, so it wasnt such a surprise that Revengeance turned out to among the best action games of 2013."
Drew Leachman writes: When Metal Gear Rising first released on consoles, I decided to skip it. One of the big reasons was the fact that I really havent enjoyed many titles from PlatinumGames before. I know, that makes me a bad gamer, but I cant help it. After spending some time with Raiden and company on the PC though, I can see I have missed out on a very fun, albeit insane experience.
Guide4GameS: Metal Gear Rising Revengeance have various collectibles such as Data Storages, VR Missions, IDs and Men in Boxes. You can collect them all in different missions and places.
