if you enjoy fallout 3 and rpgs then do your self a favor and pick up S.T.A.L.K.E.R.: Shadow of Chernobyl
truly one of the best single player experiences i can remember.
But only if you don't mind dying. A lot.
Spoilers:
Seldom hat an experience as intense as when I tried to reach the reactor first in the middle of an army raid. I wasn't even shooting at anyone, just running and thinking "oh shit oh shit oh shit" and amazingly survived on the first try.
