Bad news for Stalker: Clear Sky - it's been recalled from stores. Well, only briefly - apparently the initial shipments didn't contain CD keys, cleverly. So it's been delayed a few days while some poor sod presumably prints out a load of stickers, meaning its September 5th release date in the US ain't gonna happen.
Shacknews reports this may delay the Steam release too, though apparently the European release is unaffected. Amusingly, Shack readers are reporting spotting the game in stores nevertheless - and even if those copies don't have CD keys, I'm pretty sure the single player works without 'em. You need the key only for multiplayer, as I recall.
Oh - and you should now be able to get hold of Jim's review in PC Gamer, and my review in PC Format (both the UK versions). Won't spoil the scores, but, well, [sad face]. Kieron's also been playing it, so we'll be talking more about Clear Sky here soon, rest assured.
