I was talking as a whole as well not just about Demigod, like games for windows. If Microsoft set a standard like they do for the xbox. So all the games would have the same system implemented. It would be a lot more stable than running lots of stuff, I would assume.
Develop a GUI? All I was thinking was in the game settings you could just select a folder to play from. Running multiple stuff at the same time isn't really my idea of a great compromise. Next thing someone will say is get a stereo. I'm not asking for anything fancy just let me select an mp3 and play it in the game. They did it GTA San Andreas, I think I actually had to move the files manually but I would be more than happy with that. Sliders are usually already in the sound options.
Anyway thanks for the reply better than someone just ignoring this completely.
