I have 4gb ram, Core i5 750, and a Geforce GTX 460. The only modern games I have are Crysis (which I beat in a matter of hours, meh) and Flight Simulator X. I'd like to get my money's worth and enjoy some other games before this crap is obsolete again and I can't play new stuff. I'm open to pretty much anything that is fun and not a chore. A friend recommended Stalker Call of Pripyat. Your thoughts?
