Only games I occassionaly play are Fallout 3, GHWT and Rainbox Six 2.
Haven’t played COD4 for ages and any RS2 for over a month, I’ve let my Xbox Live membership expire, 5 quid a month richer now 😀
So, Fallout 3 is all I can recommend, very immersive and quite dark 😈
You got GTA4? I thought the SP on that was amazing, like watching a movie 8)
edit: sorry Insane 😛
