Your better off with Halo 3, so then you can play online with heaps of people, Fallout 3 is only best when its on the PC, coz then you can get mods and stuff...
Fallout 3 dude. Wait for the Game of the Year edition to come out though, so you can get all the DLC with the game. Halo is fun for awhile, but its multiplayer is overrated and gets boring quickly.
