If your going to look at any other mod for something, I'd look at Chiyu's extra.
I like how he has included some civilizations from past games, but namely, the native american ones, as I think having one Native Civ that is all-encompassing is sort of annoying.
He put colonization's LH's to good use with them. Including the Iroquois, Cherokee and Apache from Colonization(renaming the existing civilization the Sioux) was for me the best part of his mod(Tupi and Arawak of South America were bonuses). I'm aware theres an old civ addition of VD, but it hasn't been updated in awile.
If there was one other new unit i'd possibly include its the ancient cavalry as well, maybe. I think it would be cool to have classical era horsemen.
Other than that I am very impressed by the creativity with the future era.
