I don't want this to turn out into a flame war. This is most of the things that i think would help improve this game by a lot. And English is not my native tongue so please be gentle of any wrong spellings.
Misc (World)
* Make us be able to actually have conversation with NPC's. Offend them, make them happy and so on..
* Disable the "Auto-talks" feature. Am pretty sure that most people here just don't bladder out anything to the first person they see just run by them.
* Stop treat us like crap. It really don't matter, RP wise if you are a newcomer or the leader of a "guild". They still treat you like nothing.. So far i have only tried out Mages College, Companions, Dark Brotherhood and Thieves guild. Not sure if there are any more to join but they do at least treat you like crap.
* As for now there ain't really any perks of being a leader. You cant send people of to missions for example. The only perk (really small though considering the effort) of becoming a leader for the thieves guild. Is the small amount of gold and a gemstone that is generated in the guild master chest once now and then.
* Make it more interactive to be married. Marriage is even more useless in the game then it is in real life. And make re-marriage able as well. I mean i forgot to visit my in-game wife for 90 days. And not a word, no nothing. Not even a courier searching for me to deliver a note. Am pretty sure my RL wife would be rather pissed if i did that to her

* Make sleeping/eating more.. Viable? Am not saying a player is going to be forced to eat/sleep. Make buff food? Increase stamina and magicka regenenration if you are well slept for example. The little things can make such a difference.
* Easier Home decoration

* Need / Want to put firewood in the fireplace. Why cant i do that? Why won't the wood burn up?
Some other changes:
Okay am a brute warrior, the leader of the companions and ontop of it am a werewolf. I have full daedric (No i don't i hate it. But many here do have it. Yay for them..)
And still not even beggars look up and are envy, impressed, scared. I solo handed (pretty much) killed Alduin, the world eater or whatever they call him. Can't i have atleast SOME respect? No the world goes on as if it was no change.
* Make a small celebration, maybe even a cinematic when the player reach the first hold he/she visits. Where they shout and cheer at him/her. Make even a small statue resembling the character in that town that he/she first visits. To honor the character for the efforts. I mean its really not a "small task" to ask from someone.
This pretty much covers any type of character you play.. Warrior, Mage or as me, assassin.
Crime changes
This is the part where am most familiar. Am really no dungeon crawler (i do it but not very often)
Example;
From the dark brotherhood and the night mother i receive my contracts. So i have killed say 15 Shield-maiden's in Markarth so far.
On top of that i have also stolen around 10.000 gold of stuff (And gold) from the same city, from the thieves guild quest's.
And nothing, the guard's are not worried of this massive crime spree. Not even a wanted flyer for the times you might get caught and make a leg for it. You can kill everything in a city, run.. fast travel, fast travel back.. The guards arrest you, you get out and they still treat you the same.. Not even suspicious. They like; "Oh hello friend (who killed 20 people in the city and stole tons of goods) how are we today? You want a sweet roll?"
In short; Make the world interact with your character's actions. Make us pay dearly if we get caught, make the guards paranoid when am around after ive been sent to jail for mass murder / Mass theft. Hell make even a guard follow me on distance for a short time (Or i make my good deed for the jarl / Steward / whatever)
