I just got CS:S and I am pretty impressed with the game. I used to think it was only for hardcore nerds or something but it is a pretty fun game. Although I haven't played that much of it yet, I just hope I don't get addicted to it - my grades are already bad enough, and I don't want to have a repeat of my former Guild Wars addiction. lol. I also like Half-Life too - the single player is amazing, although I heard it doesn't have much replay value. But the story is so emotional and it feels like I live in that world or something - it's crazy. Also, I have been playing S.T.A.L.K.E.R. SoC. I love the FPS RPG hybrid. Kinda reminds me of Oblivion - with guns!!!
