I play game after game where the Mimot absolutely steamroll every other player. My last game had the Mimots with 10x the power of their nearest competitor. How do we compete against them?
Been playing a step or two above "normal" and I have yet to see the Mimots win a game. Honestly I think this may come down to galaxy settings. With my galaxy settings everyone starts in a sector with 3-4 neighbors. I find that they expand too quickly and get themselves into a multi-front war early because their growth rate exceeds their diplomacy.
In my current game, at turn ~300 they've only had a single planet left for the last hundred or so turns. The Festron wiped them out. Actually, my last game, IIRC the Festron wiped them out also.
Honestly, the faction that I see do consistently the best, game after game after game, is the (Iridium) Corporates. In my current game they wiped out the Yor who had taken 3/4 of their sector and eliminated 2 AI's there. They always seem to push hard, and can field much larger fleets than even the strong production civs (ie Yor, Drengin) with their unlimited buying-ability.
It would be interesting to see what data SD has on how the factions tend to do over-all...
IMO the Mimot are pretty good, but a big piece of this is that it's impossible not to use their cool ability (double ships) - you wouldn't even have to code for them to do it. Same with the Iridium, if you think about it. The strengths of the other civs, by and large, are a bit more subtle than that. When all of the AI's can fully exploit their own unique strengths, then I'm willing to discuss whether one race is better than all the others. I should note that the Festron tend to do pretty well also..
