AI doesnt seem to deal with the metal/crystal extractors in asteroid belts and the such (off the top of my head I dont think I have seen them take one). When I capture them, they simply ignore the fact that they are there. I had some in there territory and could see the fleets moving about, however they never did capture them.
I've seen it happen once, on a single extractor, in a 1v1 map. But they sure don't pay them any mind. Jikara Navigators jumping in and out of an asteroid belt and not a single one can be arsed to try and take my mining colonies away from me.
I'd like to be able to have a mode were you start with the most basic things. A couple of planets, 2x military, 2x civilian research stations, mining buildings on all available asteroids, 5 frigates, a capital ship building. This would ofcourse be a kind of a 'get into the game fast' kind of mode. My main problem with this game is that it takes so long before you actually get to really play for real.
A quick-start option would be very nice, I agree.
