If you have any interest in Condition Zero, you should seriously consider getting Counter Strike Source instead. I ended up with Valve's Platinum pack several years ago and I have to say, I never even bothered installing Condition Zero, I skipped straight to CS:S. I think if you bought CS Source seperately, you can get it for as low as 10 bucks. No joke.
Don't play a game using the Quakeworld engine. (GoldSource, or whatever the heck they wanna call it.) Spare your eyes the strain. It's 2008, not 1997. They only used it then cause it was the best of what was available.
