That's interesting... I'll have a look. Not expecting much, however, since this issue has been ongoing since way back and not just with this game.
As for whether it's any good, 'Clear Sky' is generally not rated as highly as 'Call of Pripyat' or the original Stalker game, but I bought it so I want to try it. There are mods-a-plenty for these games I know, but first things first
