I disagree that the dungeons were poor quality, but I agree wholeheartedly about the lack of enemy variety. To me, the problem wasn't the dungeons themselves, it was what was inside them.

A thousand Lizard Men and a few of those dinosaur creatures got old real fast. It was bad enough that all the Lizard Men had the same equipment. I'm hoping the bestiary is something PB has really worked on in terms of variety for Risen 2.
