As a fan of the S.T.A.L.K.E.R. series I was overjoyed when this game came out on PC, however there are some things to be aware of, namely the 'compiling shader cache' at every start that often fails, and some game breaking bugs — luckily there are some clever folks out there that have solutions to the ones I have encountered so far! If they can fix the shader compilation glitch, and if it was the original voice actors from Clear Sky/Call of Pripyiat days then I might even give it a 10, but until then it's still too buggy to rate higher.
