Some games I want buy for my pc, and some for my PS3. FPSs, like Bioshock, Crysis, Oblivion, etc., I like to play on my pc with a mouse and the WASD keyboard. Some games, like GTA4, MGS4, etc. (TPSs), with that over-the-shoulder-view (OTSV),I like to play on my PS3 with the DualShock Controller (PS3wDSC). I want to pre-order Fallout 3, but I can't figure what it is? What system should I get it for? Does anyone know? DAK?
