Something more to sink my money into by contributing to the community of a city my house is in - take the orphanage and its four orphans. My good but eccentric philanthropist character has too much money and is looking for good causes to become a patron of. Improve the orphanage (think of all those immortal children whose parents died fighting dragons!) or become a patron for a theater for example. Or build a library.
Or maybe the ability to fund an explorers club. They could go out and bring me rare alchemical components (the more I pay them the better their chances of bringing me good stuff and not getting eaten because they'll have better equipment and hire better guides).
NPCs should recognize your race. Thalmor agents speak to my Altmer is if she was a puny, inferior human and not the Master Race specimen she is.
Indeed!
And that should be easy to do (the second part) race was recognized in Morrowind with corresponding slight disposition change and comments.
I think that could be a good thing, there was a Morrowind mod, Rise of House Telvanni that did pretty good with you guiding house Telvanni in how it dealt with the mage guild, the Company etc and many other things shaping house Telvanni's place in Morrowind society.
I would like more logical inter faction conflicts, make you think about who you choose as you wouldn't get to be boss of everything. More options of how to approach a guild - join them or resist them (probably best for "illegal guilds" like the Thieves Guild).
More lore on the Thalmor
In game books that mention the events of Infernal City and Lord of Souls
Yes, I will never get enough books.
