I still have a wild idea for a future combat game. U.S.A. reduces its world influence in order to focus on internal development, mainly newly discovered fusion power. It is very costly at first, so it can't be helped.
During that time, Russia and China find themselves competing for the spot of top supreme nation. They have to truly secure that spot before U.S.A. can get moving again after it does its fusion conversion. But, where U.S.A. has more or less tried to be world police, Russian and China are not so kind. Things go bad between the two, and well, future combat game.
P.S. On a very different note, why the heck are gas prices sky rocketing?
