Nobody should criticize Valve. They should spend some time trying to make their games better. If you are going to criticize Valve about their gaming policy, you better be named Miyamoto, Kojima, or god.
I don't think Miyamoto could criticize Valve... hes never tried to port anything on to PS3 either.
Like it or not, Valve, ID, Epic and Bungie are the top tier developers for FPS games with Valve being number 1 in my poinion.
Monolith, Gearbox...few others are trying to be like-valve but are never as good so they have no business in criticizing their games. Howeve rthe Gearbox prez is criticizing their lack of PS3 support...Im not sure how to feel about that. He is partly right I guess...
