"The original S.T.A.L.K.E.R. was one of those PC titles that had gamers excited, but unfortunately succumbed to years of delays before it finally launched last year. Fortunately, the extra years in development were kind, as the game delivered on expectations with compelling action-RPG gameplay and a great environment to explore. Considering how long it took the original game to come out, it's somewhat surprising that developer GSC Game World will have the follow-up ready to launch so soon and sure enough, S.T.A.L.K.E.R.: Clear Sky will be out this September."
