Rogue-like encounters is one of the best mods I've used. It adds soooo much diversity to the game and many monsters are handplaced around Skyrim. It uses creatures from SIC, monster mod, Mihail mods, and more. The full version would probably conflict (lots of combat and magic changes) but there is a monster only version (and a lore-friendly monster only version). If at all possible, I think this mod would be a must-have for SPM5!
As a side note, is there anything we can do to help out RottenDub with development?
