No, I don`t. Brand new Skyrim on Amazon = ~25E (boxed, not a "license to play"). On Steam = 49.99E. Similarly to Gamestop & Amazon, Steam is powerful enough player to negotiate prices. But since they cornered the PC market, why would they? They`re so "cool" their customers will defend those high prices themselves - which is quite a paradox.
But don`t worry, I won`t go into a 3-page argument about Steam in general, there was enough of these all over the net already and there`s little point preaching to the converted. If not for the BS that is Steamworks I would probably use it myself, for bargains & some indies , even while disliking/questioning it. After all I use Microsoft`s products, or some other stuff from people that I don`t agree with - but I also don`t try to excuse them or worse, pretend they`re actually the good guys.
