Awesome graphics and FPS/RPG style. It's like everything good about Fallout 3 mixed with the graphics of Metro 2033!
I have completed the game twice now and it was actually more enjoyable the second time through. I really can't say that for many games over these last few years. This was my first experience with the S.T.A.L.K.E.R. series and I was very impressed. Since finishing I have gone through and played the first two games, Shadow of Chernobyl and Clear Sky and these are also awesome FPS/RPGs. If you enjoy CoP you should definitely play the whole series.
