soccerdude2, great minds think alike!

halo world any of em would love to be a marine and bust some heads.

I would definetly live in the pokemon world, because I always loved the pokemon games until Black and white :(

hmmm
i think in the spyro worlds =')

Farming Simulator 2012 anyone. Just riding around all day. Doing nothing.

No but seriously I would want something as close to real life as possible.

L.A. Noire, Godfather 2 or Mafia 2 :3

This depends, if I chose Call of Duty do I re-spawn like Call of duty?  Assuming re-spawn is a yes then I would live in the following games:
1) Call of Duty - I would for sure be either a sniper or a rusher
2) World of Warcraft (NOT MISTS OF PANDARIA, PANDAS ARE HOMO) - I would **** straight be a Restoration and Elemental Shaman or a Rogue, can I be both? 0.o
3) Call of Duty Zombies - Who wouldn't want to live in such a world?  Beats the hell out of going to school then straight to work then staying up until 2am to finish homework only to get up at 6 and repeat.
4) GTA - as long as I can re-spawn then who doesn't enjoy a little anarchy?? I don't care if I can feel the pain as long as I respawn I would do this **** all day.
5) Call of Duty World at War - okay this is kind of breaking the rules but I would be Hitler any day!  Most of you right not are like "WHAAA?" yes that right.. your so astonished you forgot to say the "t." but in all honesty if life was a game that means everyone re-spawns not just me, the world would be anarchy and what better way to enjoy anarchy than to be a world top anarchist???

I would say the world of mass effect because at least maybe i could impact the world enough to get a better ending

Mirrors Edge
who doesn't want to do parkour!?

Sly Cooper! Preferably episodes 3 and 5 from the Sly 3 and episode 1 from the Sly 2.
