The first Condemned game was very much a 'sleeper hit', even I didnt get round to playing it till a lot later on (when it was priced at only 15£/30$), but I loved it more or less from begining to end.

I consider myself a connoisseur of the horror genre, and I believe Condemned 2 to be one of the best games in said genre. If you're looking for a game that can issue tense, white knuckle atmosphere ...
