What's been added from morrowind to skyrim?
I'm curious because I haven't really played morrowind much.
Mostly, the world is a lot more "fleshed out" - Bigger color palette, to the dismay of those who love all the shades of Brown Morrowind had (Vibrancy? Heresy!), more unique NPCs (Honestly,
Morrowind had rather few memorable NPCs outside the main quest. Now, had the writers bothered to focus on the little guys instead of feeding Micheal Kirkbride's Gary Sue...), living towns and believable economies, observable culture-in-action (In Morrowind, there was once a lot of interesting stuff going on, but then everyone forgot how to sleep, and started walking around the same place), more places of interest, more information on the places of interest, personality added to otherwise insignificant characters...
On the mechanical side of things, as much as I dislike them removing "Acrobat" as a character type, they've greatly increased the number of ways you could define your character, especially for the various flavors of warrior and thief. Perks allow you to define your take on the assorted skills - how you handle a shield, meaningful weapon choice, what your armor means to you, etc.
Dungeons have much better design, with more thought into the encounters, areas-of-interest within areas-of-interest, loot distribution, puzzle solving (Alas, none of the legendary hidden temples feature The Shrine of the Silver Monkey in them), and meaning to them.
Identifiable food.
There's a greater ability to be self-sufficient in the wilderness, and bug-hunting never gets old for me

(Why do I keep killing the bug, though? I wish I could get a glass jar to keep them in so they can flutter about merrily

)
Companions to complement less self-sufficient character types.
Quests are also much better, diverse, and plentiful, even though the "Guild" quests are much fewer - There's a world to explore out there, stop waiting for someone to tell you what to do!
