So, I would really like some mods that add a little more to the RP aspect of the game, as well as some little things that I would just like to see in the game. So first of all, I play a couple different types of characters but mostly casters, so a lot of my requests are geared towards that, though I also play a heavy melee and a stealth character.

1~ I would like some mount expansions. I would really love if someone could add Snow bears, red elk, caribou and Mammoths to the mount list. It would be cool if we could put armor on them, but not necessary. As for the mammoth it would be cool if you rode in one of those Howdah seat fortresses like http://www.forgeworld.co.uk/Images/Product/DefaultFW/medium/Mamm1dflt.jpg or http://www.probertencyclopaedia.com/j/Howdah.jpg though obviously not so elaborate (unless you want it that elaborate... ). I mostly really want the snow bear, as it is part of my Ice Druid rp character, and I would love it very much. Also for mounts, I would really appreciate a call mount whistle that summons your horse/whatever and a no combat mod to stop my horse from going to "get some" and then dying because that is a freaking dragon you are trying to kill horse! Stop that!
2~ There are some really beautiful caves that I would love to have a player home built into like the Eldergleam Sanctuary. A house like that would be a perfect place for a druid. Obviously you would have to clear out the locals first, most likely spriggins but what good house doesn't come with a little work?
3~ I like the giants... A lot. I want to be friends with them. I would really like it if you could build up a reputation with them, and maybe they could sell you stuff, or offer protection, or they could sell you mammoths.... Anything really would be cool I just want to have an alliance with them instead of they are there to heard mammoths, take up space, and sometimes be the subject of my bounty... that is crap. It would be cool if first you met a giant who spoke very clipped "common" and he told you to first learn their language to start building a relationship with their clans. From there you would have to hunt down books on their language and history, then you could unlock dialogue with more of them and build up an alliance from there (obviously they would speak whatever language your game is in, you just unlock their dialogue by finding books on their language and "speaking" it with them)
4~ Even more customizable options in character creation. A lot of the hairs and war paints are the same across races and genders, and I would like some that are more race specific.
5~ Themes! For houses! Fallout 3 had it, and it was great. I would like a more dark elf theme for my house, or maybe a Khajiit or maybe just the theme of a different hold. Maybe I want a Dwemer theme for my house in Solitude... You would pick a theme, and from there buy the rooms in that theme category.

If anyone thinks they can do this, please let me know. And if you have anything to add to the list, feel free, it would be nice to have good list going to see what is most requested.
