Well yes, all games should be on a platform that is available to anyone, the PC is the closest thing we have to this (even if MS owns windows, nothing prevents Sony, Nintendo, etc. to to like EA if they don't want to use Steam).
That would be great! no more consoles, just PC stats wars and 3D marks scores pissing contest!!
I want to play the last of us at 4k (supersampled to hell and back) 120fps!!!!
Do it Sony!
