My idea of a DLC is where you can venture to other parts of the world such as black marsh, cyrodiil, morrowind, valenwood, hammerfell, and elsweyr. to see every part of the world you hear and read about, a good size quest in each territory to keep you busy and give you a taste of upcoming games? whatever the case it will be fun to access some part of each place do a little quest bring back some nice armor, weapons, random bits of metal, alchemy ingredients, and even some recipes for the forge and something to cook. bring everything you have and learned back to skyrim!

Make a name for your self in each place by doing some small side quests, be welcomed or shunned for your race in certain places, own a house in each place to come back to and visit, a follower to help you in your quests if you want, a special horse native to each land or whatever else they use to travel? Have a stable outside your house for the horse to stay in or whatever else it may be.

Be allowed to take whatever you want to each land but be warned some fractions are more shunned then others and can result in being attacked.
(wearing Daedric armor in a holy land? have hired thugs attack you for it)
(Dark Brotherhood armor in morrowind?)
(Being khajiit in Valenwood?)

I understand the race thing may be a bit extreme as it is something you can not fix so maybe just shunned by words from certain NPCs.

So what are some other things that can be added? Any ideas to add, some concerns? Also sorry if this is a repeat thread I am still getting use to posting and this is my first topic please use spoiler tags when necessary. Thank you.
