After a few restarts for bad start positions I allied with morgan, who happened to be doing very well. It's basically Spartans+Morgan (I'm sparta) against the rest of the world.
I got chaos guns early, and Morgan supplied fusion power, so I absolutely steamrolled the sea ports of University and a Northern expansion of the Peacekeepers. I think I might have to knock it back up to Thinker after this round. I'm going to be busy consolidating my conquests (they were all around the monsoon jungle island, and the AI is terribad so they're extremely high population with little terraforming... I'm shipping in land terraforming for MOAR BOREHOLES now).
I generally don't play with tech stagnation, and I play with conquer = steal tech (which gave me a nice couple from University when I stomped them, but only got spaceflight from UN)
