hey, I had so much fun in caveman2cosmos in civ4 and I would wanna something similar for civ5, in shortcut, it is mod that adds prehistoric era before ancient, and several future after modern (nanotech, galactic, cosmic etc.) and I am looking for some content expansion similar to that, which would lead to longer games. c2c mod has about 1000 techs and so many units and I am wondering if there is similar thing for civ5
