I got another wishes to C 3 economy. It would be fine when players will not build one megapolis which looks bad. In C3 game player could build more faraway towns cetres. It could be interesting build TC and houses close to mines, these will offer more dwellings for miners, then mine upgrades could grow up mine capacity. This way megapolis would not necessary, becouse resoucres could be locate in far away places from strating points. Stone walls in real world were never build around the forests, quarries and other resources locations, accross all map, fom border to border. This case needs improvements in the game. Then outposts and fortifications as like bastions, castles, forts, fortresses get more sence. Gold mines are not necessary in the game. Players could earn gold from manufacturing and trading. This is way bettter than rich gold mines in the game. Gold mines in Europe were very rare and poor at that period. Therefore gold mines in the game are not necessary. Craftsmen, manufactures, factories, merchant ships and trade are much better than few gold mines. Such mines require fixed places marked with yellow dots. Without gold mines there would be more free places for better development and combats.
