Hi,
Thanks for making this game! I think its really fun. This is my main city:
And this is my limestone mine:
I really enjoy the trade/multi settlement aspect of the game. I hope you develop it more in this direction, with different resources only being available in certain areas - as far as I can tell, right now the only resources it is necessary to trade are copper and limestone, as everything else can be found everywhere. Did you know that to smelt bronze requires copper and tin? Additionally, copper and tin ores are rarely found together - bronze age cities needed to trade over long distances for at least one of these ores, and some historians believe that this trade helped promote stability and peace during that period. Once iron smelting was discovered, the need for trade diminished, long distance relationships became less important, and wars became more common. Maybe you could try to model these dynamics in your game, with AI cities and sea trade. Perhaps you could also introduce luxury items like wine or incense.
Thanks a bunch,
Oliver.
