My go-to pick is Sonic Adventure (1) for the Dreamcast (now on Xbox Marketplace). It was pretty much the first game I poured my time into, and I loved how much you could do in the game. I didn't like Sonic Adventure 2 as much because while it was awesome, they made it too complicated IMO. So, yeah.

world of warcraft ^^ i like it coz it like never ends. kinect on Xbox 360 is a ****** too :D

Call Of Duty 4 Modern Warfare. PS3
James Bond Nightfire. PS2
Madden 07 and 08. PS2, XBOX, XBOX 360, PSP, etc.
SSX. PS2
GTA San Andreas. PS2, XBOX
GTA 4, PS3, XBOX 360, PC

I really like Legend of Zelda just because it made me think. It was fun to play a game that focused more on the skill of the player and less of what level you were. It was also very challenging to collect every side quest or a certain amount of items.

Super Mario Galaxy 2!Wha-hoo!It is very well designed,it has got cool graphics,colorful worlds,awesome music,nice gameplay,and many stars!It sure deserves to be one of the best games of all-time.

My most beloved possesions are Fallout 3 and Fallout New Vegas (XBOX360) Endless possibilities and you could replay forever, every playthrough is entirely different.

Pokemon SoulSilver, it really brought back the nostalgia in the series!
