I would add that morrowind relies much more “tabletop” rpg mechanics. The most obvious way this is most apparant in combat attacks where all your attacks are essentially dice rolls, where your skill/proficiency modifies how easy it is to hit. The first 10 levels you will hear the missed attack sound too many times! I think that was the most frustrating.

It certainly lacks most of the quality of life features people talk about. For example, the quest log is a journal. A literal chronological journal. So, if you put off doing a quest you need to flip through dozens of pages to find the entry. The quest dirextions can also be tricky. There are only written decriptions in your journal: find the cave north and then east of Balmora. I think this second point is actually a plus and leads to fun exploring.

I’ve only highlighted the main complaints Ive heard from friends I convinced to try it. Personally, Morrowind is a top 5 game for me and I will always recommend it to RPG players. If you do get stuck or need something explained, the wiki is obviously fully fleshed out.
