Well, took two days to wade through all the posts this time...
Inca look very interesting, but no specific/explicit potatoes or llamas, so not Outstanding. But close.
My major concern is just how well they have changed/tweaked the Map Generation algorithms. My experience with the current Starting Position algorithms has been that they Suck Like a Starving Leech.
On average, if I am playing a Civ with a terrain-linked Bonus or advantage, I have to restart from 2 to 10 times to get ANY of that terrain anywhere near my starting radius. Except Tundra. You can always get Tundra, so Russia always works.
So, since Incan city siting is all about getting the Mountains and Hills, I would assume that my first starting position will be surrounded by dead flat Tundra tiles, stretching was far as the Polar Bear can stroll...
