PC is going the way of bullshit. PSN/XBLA work for the most part cause it's these smaller games that kind of dont belong in a retail box

But with actual full retail games, you want to own the damn thing, not have a license in 10 years. Steam expects you to keep the game for life, with no selling possibility, although I think Impulse is working on a solution for that

Killing Floor was a horrible purchase by the way
