You know what I invision?........
Buying a PC game, putting it in you're computer, restarting it, and having the game boot as it's own OS, just like those consoles.... all it does other than run the game is detect hardware... get everything working correctly, give you a manager to adjust a few things.. and thats it, goes off and runs you're game, NOTHING going in the background CEPT you're game.....
correct me if i'm wrong, but thats why consoles have weaker hardware yet perform quite decently... right?
Imagine a PC doing that....
