Thalan - no farms, no beginning research/industry, nonstandard evil techs, none of the morale trade goods, but once they get going it's a massacre. Mining for 60% bonuses is just nuts, and with only a few constructors those mines are almost unkillable. On the bright side, this makes the 300% farm bonuses usable, as no one ever researches past the first farm tech; that gives a nice 16b planet with one farm.
I had two separate AI races research good & evil, but neither went on to research the evil techs I would buy off of them in a heartbeat. One is currently researching stellar marines, but I don't think they'll finish before I crush everyone else, so Tir Quan isn't going to happen either. On the plus side, the Krynn are nearly done with terror star 3, so there's going to be a bit of theft pretty soon....
