I really sympathise with these guys. The way digital disribution is going, Valve have basically set up a monopoly, and will, in the same way as Microsoft and Apple did, probably be very very hard to dislodge now.
What I see Valve as having done is very sneakily gone behind everyone's backs, and very under the table, and set up Steam before the advent of digital distribution, and I think in the coming years we are going to see their company practices get very ugly as theystruggle to maintain their vice-grip on the industry.
But yeah, Valve are teh aw3som3s, greatest videogame developers, they made half life and thus everyone must worship the ground they walk on. Anything I say will just be ignored and get me attacked by the legions of Valve fanboys, when they're not being bent over the table by the ep 3 release date.
