Another idea I'm running is a sports enthusiast. I think it'd be really cool if there were a sport similar to the zero g battleroom in enders game. The rules in the film had the teams trying to get a player through the enemies goal with each other and various fixed location obstacles in a spherical, zero gravity environment. In the film they used guns but, what with this being a slice of life game and all, we would probably be ditching that if this idea is acceptable at all. This version would probably be played a bit more like rugby/american-football with physical body checks and a ball. Sports is also something that can be participated in as a group as opposed to engineering which is more a solo activity so could better encourage player interaction.
