Here is my original draft for the submission, which ended up being over 100 words (man cutting this down was painful). I think there are some improvements made during the cutting as well, but this touches on some aspects of the game that I had to skip for the 500 word version. It still leaves our some potentially fun aspects of the game, like raiding enemy colonies (which is implied but not described). If I end up developing this concept any further, I'll post comments here.
