Probably at first I play the game to see what I like and don't like.
But most certainly I'll add some civs. But because you need a leaderhead (and probably it will take some time before the fan ones are made) for that I'll use some of the ones of the civs that got two.
The ones we know of that have two leaderheads are the US, England, France, China, India and Mongolia (the other two are probably Spain and Russia but off course I can't be sure of that

).
So the civs I'll mod in are a bit dependent on the leaderheads that are profided. But for the China and Mongolia extra ones I'll add Khmer and Korea. For the Ashoka leaderhead for india I think maybe an Sumerian or Babylonian civ. For the extra US/France/England and maybe the other two euro ones, I'll add the Netherlands

, Celts, Vikings, Turks and Portugal.
Some of the UU's in the beginning have also to be dubbled until the fan made units arive
I'll look around the barbarian civs and maybe change and/or add some. I like the idea of wild animals as a sort of barbarians though (did that allready in CIV 3 with some mythical units that were fan made).
Furthermore the religion thing I don't know about for sure how I feel about that but I'm thinkng about to add atheism for the later centuries, but I have to think about the holy city and missionary idea for that one.
