There is a open source game called Armagetron Advanced (http://www.armagetronad.net/). I'd make it portable but sadly, I'm not sure how. I have experimented but I have not succeeded. So I was wondering if anyone could make a launcher for me? Most of the game config is stored in the its application folder in the user profile, but there is some registry modification I think.
