Speaking of generic fire and brimstone, Coldharbour is pretty cool. Not the linear corridors that you have to follow in the first few quests of the main story, but the open-world version of it that you get to explore near the end. It's bold and striking, with eerie forests and blue lighting and weird enemies.
After playing the game nonstop for hours and hours today, I've finally beaten it. That is to say, the main story. I now get to play through the Daggerfall Covenant, and after that, the Aldmeri Dominion. This is made possible through some kind of magic that Meridia uses, her reasoning being that players don't want to go through the hassle of grinding a new character and slogging through the main story again in order to properly understand the conflict currently raging on Tamriel, I must see it from the perspectives of the other sides. Or something like that.
Also, Vanus Galerion's voice isn't really that bad. It grew on me after a while, and he's such a funny and likable character that I couldn't stay mad. Actually, that's one thing I really like about this game - the main characters are all pretty neat. They're far more distinctive and memorable than the ones in Bethesda's games, anyway.
