Hello,
I wondered whether the AI was calculating while I play my turn.
Chess programs, for instance, calculate while you are thinking ; they store their results and use it when it's their turn to play, thus considerably increasing their strength. Given that a single midgame Galciv turn may last pretty long (especially when there is combat involved), the AI engines would (or maybe already do) highly benefit from it. A consequence of this : the fewer AI players, the stronger they would be.
Thank you for answering if you have an idea about it.
