Top 5 (Not in any particular order, hell it was hard enough to pick 5 let alone order them!)

Metal Gear Solid 4: Guns of the Patriots

Bioshock 

Half-Life 2: Episode Two (I think I may be more excited about Team Fortress 2 than the added story bits)

StarCraft II 

Assassin's Creed

Highly notable mentions: Mass Effect, Super Mario Galaxy, Spore, Crysis, Age of Conan: Hyborian Adventures, Resident Evil 5, Alliance: The Silent War, Enemy Territory: Quake Wars, Army of Two, Kane & Lynch: Dead Men, Too Human

Hmm, probably have spent the most time on the following out of all the other games I've played:

Lemmings, Rayman, all the old Bomberman games, Tetris, NES/SNES Nitendo classics all are a pretty big chunk

Wolfenstein 3d, Doom, Quake I - III

Star Wars Dark Forces 2

Tom Clancy's Rainbow Six

Half-Life

Unreal Tournament

Deus Ex

Elder Scrolls III: Morrowind

RTCW and the awesome freebie Enemy Territory 

World of WarCraft 

(Solid multiplayer and good mod communites = long life)

 I could see if this 500 pound kid was sensitive about it but really, the best way to deal with something bad is to laugh at it.

how did you sell your gaming stuff by mistake? and future advice never, ever sell any of your old gaming stuff even the backwards compatable stuff.laughingman42

 I still regret getting rid of my SNES :'(

What else would you suggest they do in their commercials?metallica_fan42

 Not show them and while they are at it stop making the product.
