[ClearSky]

Hi @ all ,
i have a question is S.T.A.L.K.E.R. even so popular in the US as in Europe?
And who of you is waiting for the add on? :confused: S.T.A.L.K.E.R. clear sky:confused:

what do you mean by add-on? isn't it a prequel so a completely new game, not an expansion?

i haven't played it coz i'm a scaredy-cat but the first one looks good from what i've seen.
