I am not sure where it should be, but I would like another type Shivering Isle type land, that reminded us of Morrowind. I don't want Morrowind, but I want the varied lush lands and colours and "fantasy" type style landscapes like giant mushrooms and what not that Morrowind had. I would like to have more vibrant greens and blues into the landscape instead of the drab snowy tundra and snow wich we have. (on the 360, I find the snow pathetic looking when on steps or stone floors so would love something different).
Hell I would love to be able to leave snow prints on the ground. Seems so weird to be walking in snow but no trails are left behind. So much for being a "tracker" type charcater to fallow the enemy or prey.
I always wanted to visit Black Marsh. That would actually make the Argonian character be worth while for water breathing. So far in Skyrim, never needed water breathing potions yet or water walking (not even sure if it's in the game). So it would be nice to actually use the Argonian special ability. One reason why I never played an Argonian, just a wasted ability.
All I know is I would like to have more water, more bigger, deeper lakes to discover, more vibrant colours. Skyrim reminds me of Fallout 3, drab, and New Vegas more vibrant in colours. I think Solstiem might be interesting to visit, just to see how it would have changed over the years.
I think a DLC abou the (sorry forget their name) Those high elves that almost beat the empire. A DLC where you can either join them or defeat them in a Shivering Isle type size map (bigger than Point Look out since PL didn't usitlize the land very well and was smaller than SI). So maybe a place where the Altmer reside in. (damn what is wrong with me, not rememebering the TES Lore now.

)
