I look forward to that selection list! (And the dynamic history mod!) I would like to keep the Civs random. But, as you noted, with that many Civs it makes a better game if they are spaced out. In a perfect world, I would play on the really big Earth maps, but I feel like units are too slow to cross those enormous distances in realistic time on anything speed faster than Marathon. So, I play on smaller maps, and live with the consequences.
