morrowind overhaul graphics v3. It will require a fresh install of the game BUT it is exyremely easy to install, it literally installs itself.
If ur going with vanialla style, I am also going vanilla as well but ive thrown a few other mods into the mox that keep the vanilla feel. There are the sift striders, gondolian striders, and boats strider. Im at work so im hoping thats the exact name for them. Basically those mods gove u the option of cast traveling where u paid to go like normal game lr u can take the scenic rouge which u literally get to watch and ride the boat, sift strider, or gondolian to its destination. With the overhaul graphics mod, it is literally beautiful rides and feels like it should be in the game.
The only other mod I use is the morag tong armor. Basically once u get yo a certain rank in the morag tong, u can purchase their armor. It has the same def ratings as the db armor so its not god mode and u have to work towards it and it impliments some very sweet looking lore friendly armor into the game without breaking it.
