The best game i have ever played is Call of Duty 4.
The strory mode is exciting and the multi-player is phenomanol.
You never get bored of it.

It is meant to be the Best game you have ever played.
Sorry.

That's really a hard one. I think the way I would look at the best game I have ever played is one I enjoyed playing with friends and continued to play the game for years. I'm talking about WoW.... :bleh: I have since moved on, but the story line of the game is great, replay is great, interactions with others can be great if you know them and it's fun raiding.

For a shooter, CS:S for the in your face action, and 2142 for it's.....well....I like it.

Well thats a hard question but the greatest game that i have ever played would probably have to be FarCry, i mean when that came out, that game was seriously awesome. but other Favorites i cant decide form would be GTA:SA, Hitman: Blood Money, and Crysis.
