I'm curious about the community if they get all they're games legally, or if they use other "means" of getting them. Having the fact that they are an awesome game company, I buy all of mine.
I've only pirated the first one and it's expansions, but that's because A) I can't connect to steam in my bedroom and B) I couldn't find them anywhere.
I've also pirated HL2, but I own the Orange Box for the 360, so I have no moral problem with it.
