i second the game fear!! one of my favorites. it's freakin scary imo. you could start out with fear, then they have 2 expansions, and it's just as scary, but fear 2 has amazing graphics and that damn lil girl....
and dont worry....i have both crysis games, and i am still impressed by graphics of other games like fear. (buy fear do it!) i'm gonna get the x-pac to it soon
