SlowTechAndCivics
This mod slows down technology and civics progression, so that you can enjoy every era for a longer time. And you can chill out! – An extra feature is that I have removed the (IMO) annoying fact that great people could not be killed. They would just teleport back to a friendly city. These days are over, with this mod. Watch your great people! And start killing off the enemy’s wandering great people :]
