Don't forget the Deep North, quite possibly the best and worst place to build. You get absolute peace, at the cost of no resources nearby. You get to build huge things with very little restrictions, but for no reason. Also the blizzard drops my fps like a bowling ball off a building. Farming resources from a biome is one thing, but if you want to BUILD something, definitely Deep North.

Oh, you said Tundra. It's Deep North.
