It is a bit annoying that everygame i have to play in the same way, factory, build colony ship, factory,colny ship for the first turns only to try to prevent AI colonization rush.I hope that things could be a bit tweaked like buying colony ship for player and AI a bit more costly or at least less money at the beginning.I don't know if adding mainteinance to some buildings could be a good idea but for now advantages from a fast colonization are too high, and i would to start my game without having to play everytime in the same way.
