Does this also include the "Official Plug-ins" from Bethesda as well?
No, it doesnt, I only have vanilla Morrowind.
Never could find a disk that had Bloodmoon and Tribunal.
I play on xbox as my pc is old and cant handle Morrowind lol.
And its really hard in Europa to find a disk of a game that old, though I do keep scouring second hand shops.
But on the vanilla Morrowind, I have done every quest, cleared every dungeon, found all unique artifacts etc.
I remember a few of the very last things I found were the Dragonbone cuirass and all propylon indexes.
When I finally got online I found a minor quest on the UESP wiki that I had never discovered on my own.
(Stealing a list from a Telvanni enchanter in Vivec city.) And a unique ash on Azura's coast.
Ive read the wiki a lot and can safely say that now I have finally done it all.
Took me about six years though.
