Actually, I don't know, but would like to play CS:S as long as I can play against the AI instead of going online against others. I never played a multiplayer game, so I want to test it out first. Any ideas if there are bots or some sort of offline mode in the works for it?
As for the CP, well, it was a stupid decision in this case. It already has activation required, by making it have CP as well, it's just overkill and another way to screw over legitimate consumers, while doing nothing to stop people who will pirate it. Eventually, this will bite the game companies on the ass, in the meantime I'll come here for NO-CD/DVD patches!
