I don't know very much about Valve or the games it makes but I got Counter Strike: Condition Zero some time ago and now I see Counter-Strike: Source what is the difference between these two games as far as I can see there the same, but I can see one or two differences from screenshots I've seen is Counter-Strike: Source like Counter-Strike 2 or something I also see Half-Life 1: Source aswell?!?!?!?!?!?
I guess my question really is, is what does the word Source mean in this context?
Thanks again all
