Well, MMOs are a slightly different beast in my opinion.
Skyrim does have a similar question, No Stone Unturned. It's made somewhat cheaper by the ability to fast travel from the map, but otherwise it's somewhat similar. Throw in some other mods, like say Frostfall (to make travel harder) and Requiem (to make everything else harder) and it's actually something of an achievement.
If you want a full list of differences between at least the last three games, look here, it should give you a rough idea. IMO Skyrim was way too rushed to be considered a complete game anyway (civil war...unfinished, at least two faction questlines plots so flimsy as to not even be worth it, so many bugs...) but they did show they were following up on at least some of the problems highlighted in Oblivion (levelled loot and enemy lists).
Well, Morrowind was on sale over the weekend so I installed it with a full graphic overhaul suite.
You complete bastard.
