Pretty much what the tittle says. I think Beth managed to create different environements this time arround without breaking the harmony of the province and without resorting to alien things like in Morrowind, a far easier solution than this one that would have been so uot of place in Skyrim. I'm also gonna add extra stuff, out of curiosity.

I liked Blackreach a lot, sort of reminded me of a subterranean Pandora.
