Backstory for the aliens!
Check out my post! I've written out a pretty detailed back story and justification for my galaxy's aliens.
On another note, I need to come up with names for things. Planets, colonies, what these various populations call themselves, stars and systems, ships, governments, gah. so Many names. One of the more important ones is likely to be the title of the game, so if you want to play the lotto, you guys could help me come up with names and maybe yours will be the one that ends up naming the game too.
