you know what game I liked? it kinda went away, at least u don't really hear about it much anymore was 'Perfect Dark'. When Alias first came on I was like "hmm...where have I seen this before..." and it was so cool 'cause that was my fav game!
Out of those I would say GTA Vice City. That game is just so much fun.
My second choice would be Diablo 2 LOD. I have some pretty good characters on there but I havent played in forever.
