How do the AI's get weapon techs so fast?
When I play a game of GalCiv, inevitably at least one of the AI's will get weapon tech's super fast, like Laser I, II, III, and IV after six months or so of game time. That's barely enough time for me to get to level one of a weapon. How is this possible? I play on 'tough', so the AI shouldn't be getting bonuses or anything...
