I've found something very interesting. A mod that overhauls dungeons in Cyrodiil.

Download it here: http://www.oblivion.lima-city.de/files/plugins.html

I'm downloading it. In screenshots it looks awesome! Much better than Better Dungeons!

I'lll play it. Not sure, if it's compatible with mods like OOO, MMM. Some creatures can be stuck in rocks.

Let's play it, no more boring vanilla Oblivion dungeons.
