I want to refresh the Discussion:
There are many good old Games on of course GOG. I want only to mention five Titles:
Riddick
Sid Meier's Alpha Centauri
Master of Magic
Panzer General (I know there's Panzer Corps)

Arcanum: Of Magic & Steamworks Obscura
I registered on GOG for this game only :D

Halo 1-2, Noone lives forever 1-2, Alien vs. Predator 2. Though these ones should be released on gog as well

Fable II, I know there's no PC port for it, but there needs to be.

Oh, also Soul Calibur.

Anyone, Origin, GoG, Steam to sell Gladius. Man no one ever remembers that game but it was so awesome.

Games missing on Steam? Epic console exclusives (the games themselves are epic but the fact they are console exclusives is pretty sad and not epic at all) such as Metal Gear Solid IV, Gears of War, Danganronpa and others. These games are awesome but the small quantity of them does not warrant buying a console (and gaming computers are totally better than consoles).
