I've gotten around to generating the balance stats automatically. You can see them
here. Right now there isn't enough data beyond about 30 games, so the 40, 50, 70 and 90 plots will look the same as the 30.
Overall the balance isn't too bad, but as you can see it's still significantly biased towards the aliens. It does however seem to scale fairly well now that I've filtered out redundant data like games with fewer that two players.
