I came across a sci-fi strategy Stardust Colonies on Kickstarter, the developer seems to be very passionate about AI, which is quite interesting. The game is like a normal RTS but each unit has a job preference and doing a specific job therefore affects its happiness level, which in turn affects how good it is at the job it's doing. If you don't manage your units properly, the whole colony will die of hunger before you can complete your mission objectives

There is a link on the Kickstarter page to download a free demo for Windows, it has 4 campaign missions and random map, although there are only temporary 2D graphics in the game at the moment. In any case, it's hours of interesting and fun game play!
