I have played seven of Bethesdas rpg games. Here are my rankings and ratings.
1. The Elder Scrolls V: Skyrim 9.5/10
2. Fallout 3 9/10
3. Starfield 8.5/10
4. The Elder Scrolls IV: Oblivion 8.5/10
5. Fallout 4 8/10
6. The Elder Scrolls III: Morrowind 7/10
7. Fallout 76 4/10
The only game I haven't played 200+ hours, (Skyrim is just under 1800 hours), is Fallout 76. I never quite got into it. But the 20 hours I spent were not enjoyable.
Even though Morrowind is in sixth place, it is still miles above Fallout 76.
