How do I play on the Huge Earth map that comes with the game, but with differenct civs instead of the standard 18?

Huge noob question, but I totally appreciate any answers y'all can give...

For a start, you need to read the forum rules... :P

New threads are for new Mod listings ONLY. From there, if you want to post about that particular mod you post in that mod's thread. If you have a general query about the game, try in one of the more generalised Forums.
