Wing Commander
Considering this game was out in the heyday of the NES, I once again am convinced of DOS' superiority over nearly everything of it's time.
Then again, it's from Origin, so what can I expect other than total perfection?
Oh, and Homeworld. This game is so awesome.
And Unreal Tournament.
And the constants, which include but not limited to: Descent, Duke Nukem 1&3D, Doom, Civalization, Master of Orion, and Privateer, if I could get it working.
