Over at Network Node (
www.networknode.org), under custom factions, Zeta set, there is an "alien civil war" series, featuring 6 alien factions and one overpowered human faction. The Aliens go at it. If you even make friends with just one of them, you got 5 aliens at your front door. not funny. If the human faction wasn't so overpowered, it would quickly find itself in a huge heap of pincers in a hurry. Makes for an interesting game, I'll tell you THAT.
If you really have a yen for playing that, try it. I have.. it's fun. Nice for a conquest-type of game.
