I hope I'm not breaking some kind of rule by posting this here, but I am looking for a type of mod that does not seem to have been made yet. In short, I find the mechanic that raises the costs of Virtues and techs the more cities you have to be nonsensical at best, and would thus like to request that somebody make a mod that removes the penalty.

I would do it myself, but I don't know how to mod the game. So, I'm asking you. Can you help me?
