Please explain how VALVE games are tied into Steam, even retail copies, is competition. If I bought a retail copy I would like to run it without any Steam interaction. What I see is that it's their game and they can pretty much do what they want with it. To expand on it. The only place you can buy Left4Dead or Portal is either retail or Steam. D2D don't have them. When you buy retail you still have to install Steam to play. EA is simply doing what's the compettition doing with their own titles.
