I played COD4 for a year and got to Gold Cross 55 (insert "big deal rookie?" comment here). that was my first FPS. I tried Resistance 2 and didnt like, I am trying COD: Workd at war and seems like aiming and controls are off? I want another game and cant tedcide between: Bioshock, Dark Space, Fallout 3, Far Cry 2 and Socom. Anyone have suggestions?

Additional info: mainly getting for online play?
