Add epochs for cities

[TheNewRus]

I would like to be able to play for a certain era (antiquity, the Middle Ages, etc.) so that each time period has its own special feature (for example: textures, as well as the absence of landfills, plumbing and energy in antiquity).

I thought about it too, only as a separate regime.

Hmm i dont think so

[Resp]

The idea is not very good.

It's a good idea, but how to implement it?
