They should start going back now. Do Morrowind next.

Morrowind remake with Bloodmoon, Tribunal, and new additions on a map larger than Skyrim, in a self-contained portable VR set that also works as a handheld and PC. I will pay $10k for that if I have to live in a cardboard box.

Tamerial Rebuilt, the Cyrodil mod, and the Skyrim mod, with either the Script Extender or with the OpenMW engine will do all of that for you.

Good to know. How do I get started learning how to do all that?

Start here!
