CS 1.5 and 1.6 are the best imo. This is the most played game in the history. WOW is far behind it. Actually, i read an article some time ago, saying that CS is the first game created that has so much physics and maths in use and it has a revolutionary engine for its time (the end of the 20th century). I know that my explanation sucks, but u get the idea. I think that all the versions of the game after 1.6 suck hard, personal opinion. I dont like this one either.Cheers...
