Im a grumpy old man, whats worse, I enjoy being one.
Well,there is always room for change,who knows

I do like your posts though, the emoticons make me smile.
Better than nothing
Size of the worldspace.
reputation system.
unleveled enemies.
Text dialog that is far more moddable than voice ever will be.
More length and depth to quests and quest lines
Branching quests, with decisions you make opening up or closing off other quests/locations/guilds/whatever.
Spellmaking.
What was not in previous games, but -should- be, is sense and useage to the minigames like milling, smithing, farming, hunting, etc. If you have the option to hunt, there should be a need to do same, for example.
Minigames should have been more "captivating" and challenging in my opinion.
And adding things like gambling on a struggle or strong-arms in the inns would have added "more life" and immersion.
I don't want the Fable" things of course,but i think that those activities would have been well fitted with the nord environment.
And even the whole Bard's Academy thing is pointless and unfinished at the actual state,'cause at first i was excited to the opportunity of being able to play an instrument in the game. Opportunity that have faded away irreparably in few quests sadly.
However if we talk about "new gameplay features" an hardcoe Mode like FnV with karma etc. and a scaling system applied only at certain "High levels" were "priorities" for me - together with other things already mentioned in other similar threads regarding the lack of depth in contents/writing.
The "worldspace" is alright for me.
