Having spent a day playing it at after Futureshop broke the street date, I can safely say that Clear Sky is a buggy mess and takes a few steps backwards from the original. What a disappointment, last time I buy a game in the Stalker franchise. I had hope they would've learned from their mistakes with Stalker but Clear Sky appears to have had zero QA.
Playing: Xenoblade Chronicles DE, Ys IX, God of War
Watching: Lupin, You me and the Apocalypse, Days of Thunder
