I haven't played it in a long time (I pretty much lost interest after beta 3.1, which was the most fun of all the versions), but I'm sure it'll take over my life again once I get CS:Source.
omg dont listen to them Unreal Tournament sucks....I played Counter-Strike for 2.5 years its by far the fps game on the market....along with Day of Defeat which is more realistic oriented
oops oh well i remember playing it when i got half-life when it came out, heh i don't know if it was beta or not but barely anyone ever played it then..
