Pherim: That's partly true, yes, but it is also undeniable that with each new iteration, they get more and more streamlined and more features are getting dropped than added. Every new Elder Scrolls since Daggerfall has fewer skills than the previous one, attributes have been removed completely in Skyrim, just like custom spells. Enchanting and Alchemy have become less complex and thus more restrictive. Not all changes are bad, of course, and there are definitely people who prefer the later games just because they are less complex. But from what I've heard about Fallout 4, it can barely be called an RPG any more, and so I have my doubts about the next Elder Scrolls Title.
It's funny you say that. Perhaps I'm missing your point, but I think my thoughts are similar.
While I played most of the way through (heavily modded) I never finished Skyrim due to IRL (baby) and the beckon of other games. When I tried to go back several years later on a completely different computer it was frustrating both to play without any mods, or to try to sort through to figure out which mods were still up to date/compatible, yada yada.
So it's not just that Skyrim is streamlined, but it was a bit rough as is, and at least on PC relied on the community sprucing it up to make it "great." IDK, maybe the special edition fixes some of those things.
Cost aside, it's similar to why I would never go back to raiding in WoW again. Who has time anymore to futz with all the add-ons it takes to do it? I maybe have 1-3 hours a day to actually play the games I have, and don't really want to waste that messing around on 3rd party websites.
