Morrowind was always my favorite Elder Scrolls game, but I’m probably biased since it was my first. The tech, while good for its time, was always the #1 thing holding it back for modern times. Hadn’t heard about OpenMW, but now I’ll have to check it out.

Not that I know of. I do a lot of native development mostly on Mint and Endeavor. I use pretty much the same tools on both and get a nearly identical experience. I’d say just go with what feels good to you.
