I thought it'd be neat to vote on which games you think are the best since the 360's launch, to now. You don't have to answer all of them, and some of them are going to be hard to choose from since there are so many great games.

Here are the categories:
-Best Overall Gameplay
-Best Gameplay Mechanic (Such as Braid's time control mechanics or Fable II: Knothole Island's weather controlling mechanics)
-Best Single-Player Story
-Best Xbox Live Game
-Best Game to Play with Friends (Games you sit on a couch and play together, you know when you're all eating pizza and drinking tons of soda. Such as Rock Band, Halo 3, GH: World Tour, and Left 4 Dead)
-Best Cooperative Game (Such as Army of Two or Gears of War)
-Best Graphics
-Best Sound
-Best Original Score
-Best Explosions
-Best Game Opening
-Best Game Ending
-Best Character
-Best Voice Acting
-Best Voice Actor/Actress (If you don't know their name, just say the character's name or look the game up on imdb.com)
-Best Use of Achievements
-Best Use of Humor (Such as Brucie in GTAIV or the games parodied in The Simpsons Game)
-Best Line (Such as "Oi! Suzy!" in Call of Duty 4)
-Best Use of Shock (Such as seeing a guy's privates in GTAIV: Lost and Damned)
-Best Achievement Name (Such as "Blue Screen of Death" from Marvel: Ultimate Alliance or "Warm Coffee" from GTAIV)
-Best Use of Creative License (Such as games based on TV Shows, movies, etc. Examples include The Force Unleashed and The Simpsons Game)
-Best Developer
-Best Game Engine
-Best Sequel
-Best Video-Game Add On (Such as GTAIV: Lost and Damned or Fable II: Knothole Island)
-Best Game (Discs, not XBLA or Community Games)
-Best XBLA Game
-Best Community Game



I might add some more on here later, but this is what I could think of for now.

Best Overall Gameplay - Elder Scrolls: Oblivion (limitless possibilities, and soo soo much fun)
Best Gameplay mechanic: Gears of War (Cover system, changed games forever)
Best Single Player Story: Bioshock (Never once did this story feel gamey or off, perfect execution)
Best Xbox Live Game: Call of Duty 4 (the class based system hooked me in a way no other shooter ever has)
Best game to Play With Friends: Halo 3 (Forge mode is a great way to just fuck around for hours with friends)
Best Co-Op Game: Gears 2 (this game actually plays better in co-op, it doesnt just feel tacked on like alot of games these days)
Best Graphics: Gears 2 (name any other game with so much detail)
Best Sound: Bioshock (the use of minute sounds and music worked so perfectly)
Best Original Score: Elder Scrolls: Oblivion (damn, it feels like a movie soundtrack)
Best game Opening: Elder Scrolls Oblivion (walking out into world for the first time changed the way I saw games forever)
Best Ending: Call Of Duty 4 (Holy shit, nuff said)
Best Use Of Achievements: Geometry Wars 2 (they added a new dynamic to the game and introduced new ways to play the different modes)
Best Humor: Castle Crashers (whats better than thinking u beat the final boss, and then a giant spider attacking you, nothing.)
Best Line: "Would You Kindly" (who didn't shit their pants the first time they figured out what that meant?)
Best Shock: Bioshock Twist (see above)
Best Developer: Bethesda (oblivion and fallout 3, some of my favorite games ever)
Best Game Engine: Unreal 3 (beautiful and solid)
Best Sequel: Gears 2 (perfected the already solid gameplay from the first and made it just that much better)
Best Add-On: Shivering Isles (Most retail games dont have as solid of gamplay or a much to do as this 20 buck addon)
Best Game: Elder Scrolls 4 (the most expansive and entertaining game ever, if you havent played it, get it now)
Best XBLA Game: Castle Crashers (this game is everything you could want from an arcade game, fun pick up and play feel, great art style, and multiplayer is a blast)
Best Community Game: Groov (drink a couple beers then play this, you'll understand)

Gears of War 2 for me.

I was making the list until I realised more than half of the titles goes to Call of Duty 4. Honestly I need to get me some other games to take some of the titles away from it so it doesn't look anywhere near as biased as it is at the moment.

Note that these are out of the games that I've played more than a few times...  Also some of these are based on the PC versions that I've played.
