Never knew this existed however I now have a strong incentive to buy Civ 5.

Sadly you have to buy some obscene amount of DLC before Civilization 5 becomes worth playing.  Played the early, vanilla version of this mod and it's pretty rad.  Probably good if you're willing to fork out a small fortune for things that ought to have been in the original game.

Black Friday sale is coming up on Steam,  might be able to pick up those dlc for cheap.
