If Bethesda/Microsoft were smart, they’d put out a remastered trilogy collection for Series X/S and PC. Yeah, lean into the meme of re-releasing Skyrim again, but also give people the opportunity to try Morrowind and Oblivion with a new coat of paint.
Morrowind would certainly be the one that would be harder to please people with, though. There are a lot of purists who prefer Morrowind’s style, but there are also a lot of people who want to play Morrowind with Skyrim’s gameplay.
That’s why I think at least Oblivion is the easier obstacle to tackle. You could take all of Oblivion’s environments, quests, and music, plop it all on top of Skyrim’s gameplay, and get an objectively better experience. Skyrim is not without flaws either, but Oblivion was just a straight-up broken game in terms of gameplay progression.
