Heh, I'd like to join in, what is everything that I need? is it obligatory to have it original?
Yeah, which sucks because I had two orginal disks and CD Keys of HL but it says that were registerd to an account allready wtf!?!
So I had to get it again, but I guess that was ok.
So Steam HL and the download from the website James listed in his first post. Thats pretty much thats all needed.
