It won't be a fps that I'd do. Most likely these kind of game will be off and out for a while because the computer won't be the same in communism.
So I'll do a game like civilization(2d) but in much better. Reason number one I'd do this game is for mass education and kids education. Than the reason is because I could have a lot of free spare time because I got no politics to do and in this case I'm going to try to develop games instead of only playing.
Also, it will be good to show how I develop games and how I develop of short for the example to any things of life.
