ActionTrip reports: "Although it was in development forever, when S.T.A.L.K.E.R. finally came out, it became reasonably successful shooter/RPG (compared to popular western style shooters, that is). Mind you, I never could bring myself to playing this one to the end for some reason... Anyway, CEO of GSC, Sergei Grigorovich now says that S.T.A.L.K.E.R. sold 950,000 units in CIS and 700,000 units in other parts of the world. In other words, that totals to over 1.65 million copies.
That's a nice little number and I'm sure the dudes at GSC are thrilled. What am I saying? Of course, they are. After all they'll be treating us to the game's expansion pack S.T.A.L.K.E.R.: Clear Sky, which should arrive later this year".
