Finished all Skyrim DLCs, got frustrated when my 100-hour Morrowind character mysteriously got deleted so now I'm ready for a close-to-vanilla main quest RP run of Oblivion.

Oblivion GOTY on Steam

Unofficial Oblivion Patch
Unofficial Shivering Isles Patch
Unofficial Official Mods Patch
Fast Exit 2

All nicely setup through BAIN.

Anything else considered essential?

inb4: I mean really, really, bare bare bare essentials. I don't want OOO or Frans or any other lore-breaking stuff. Also uninterested in high res models and textures.
