What could they add to make this game any better?

ummmm........ more stuff to do maybe? new skills? hrmm...... idk really

Daedric realms, island to the north, return to Solstheim, north of Cyrodill etc.

Solstheim. That is all I want.

They could add.. maybe.. spears, crosbows, throwing daggers, a climbign skill that makes you move more easily in mountains...

My idea for a DLC is a big quest with a huge dungeon in which your job is to rescue an egg for a dragon which gives you a quest to get it. As a reward for the quest the dragon would let you ride on its back once a day. The quest would be only available to high level characters

So much good stuff could be added

A huge dungeon with a lot of UI fixes for PC ...

You want a list?
It will be a long one.
Not things to make the basic game better since by most accounts its excellent, but things people would've liked that weren't included (and since Bethesda have time/resource limits thats understandable).
Then theres expansions with new areas to explore.
No videogame yet made has managed to provide everything fans want.

Oh add fishing. I would buy that DLC!

I know it seems boring but I like doing it in games.

HAND TO FREAKING HAND, or at least scaling with unarmed >.>

Only thing I really liked about WOW

Fix what seems broken?

Get Obsidian to come and do the DLC, they are awesome at DLC.

Imagine Obsidian in the Elderscrolls world doing a DLC similair to Old World Blues

new combat system, more engaging environments

Spears. Spears, spears, spears. And then some more spears.
Seriously, it's just criminal having us play as draconic warriors without being able to use a spear.

that gave me a better idea, baby/tiny dragon pet

but failing a friendly little dragon, i want to travel the sea of ghosts

Monkey DLC. Monkey race, monkey NPCs, monkey quests, monkey town, bananas, monkey swords and armors, arena full of monkeys...

My original thought for a DLC: Bring back the Shivering Isles. Updated I think it would look really neat and if they did a whole new thing with it. But thinking more about it, it would be cool to see something new brought to TES series. But I've been thinking the same thing kind of, wow, how do you expansionize this game?? I have a long ways left to go in the main quest and so I might think of more ideas by then. One thing's for sure... DLC for this game is going to be epic. I hope it is a mix of Fallout and Oblivion in that it has a really big expansion, and plenty of smaller additions. As far as updating goes, only three things so far irk me: No footprints in the snow-- rain is still not dynamic (it goes throgh surfaces!! argh I couldn't wait for this to be fixed in Skyrim and... well)-- and if I press X to get on my horse on the right side, I want to climb up the right side, not teleport to the left. Still, even with any tiny glitches and bugs this game is a solid, easy 10.

Not enough monkeys
