@Fearabbit - By Morrowfying Oblivion, my original intent wasn't to add Morrowind creatures, items, etc. My original intent was to add the depth of politics and whatnot, to make it feel as real as Morrowind feels. Hence the name. But people are suggesting armors and whatnot, so I feel somewhat obliged to provide them with it. Perhaps add border forts or villages, such as a for near the Morrowind border with Ordinators. So yeah, I feel that people are taking the Morrowind part of the name too literally, but I want to make them happy.
I guess people were taking the Morrowind part of the name too literally because
you didn't give any general idea of what your mod is going to be about. Atmosphere can be achieved in many, many ways. You said "I will make a mod that brings back Morrowind's atmosphere, but I need suggestions", so of course people will list everything they can think of that has to do with atmosphere. However, Morrowind was supposed to be alien and mystical - it's easy to create atmosphere when you got giant mushrooms, flying jellyfish and crazy gods on your side.
The difficulty with Cyrodiil is that you have none of these things, so how do you make a relatively generic medieval fantasy setting interesting and atmospheric? From your posts I understand that
this is what your mod really is about. The people here (mostly) only offered ideas that come to their minds because they assumed that
you didn't have any, but if you have such a detailed idea already, that is a whole other story, and the responses would have been very different if you had mentioned that right from the start.
This is not meant to be an attack or anything, I just want to explain why you shouldn't care what the people here suggested, because it kind of wasn't on topic.
If you had described your idea more exactly, I wouldn't have mentioned the guild advancement system. I would have said something about http://www.gamesas.com/index.php?/topic/1096460-politics-of-tamriel/page__view__findpost__p__16019413.
