I have played Skywind and while I enjoy it from a sort of "it's fun to mess around with" perspective it also changes too many of the fundamentals. It's basically just an addon to Skyrim, whereas I want Morrowind with a couple of small changes.

edit: thinking about it now I could also go for the original Deus Ex but with a facelift.

edit edit: also I want Arena and Daggerfall with combat/graphics updates.

triple edit: throw Fallout 1 & 2 into the mix.
