Wow, I absolutely love the new update! It launches
fast now, and the AI actually knows how to expand early in the game and be challenging!

Great job guys!
I was wondering if it would be possible to increase tech costs (like at around +3%) per city that a civilization controls. I understand maintenance is supposed to prevent "more cities = better civ" in some ways. However, with all the financial buildings and resources it is very easy (on Prince and Monarch, anyway) to be at around 70% research most of the time. More cities equals more beakers, so I find myself well ahead (almost by half an era) of the topmost rival civilization in technology. Thus, the game isn't all that challenging coming around the Renaissance after a few ancient and classical wars have been won and I am practically triple the size of the largest rival civ.
Definitely make this feature optional, as I am sure there would be objections to the "Civ V" approach to increasing tech costs per city. But that in addition to maintenance, in my opinion, it would add another layer of strategy in challenge to the game.
Thanks
