I hate the swamp and the mountains, boring dreary slogs the both of them. Though frost caves can be interesting. There's nothing wrong with the meadows or black forest, but they're both boring. Plains I actually started to have some fun raiding fuling villages, unfortunately fuling are pretty dumb and there's only so much black metal I need.

The ocean is by far the worst, why yes I do enjoy waiting for 30 minutes for fog to clear instead of playing the game I loaded, how did you know? /s

Wait, what was the question?
