I would love to have DLC where I could set up, name and run my own shop. There could be shop related missions and you could just dump stuff into your shops inventory and rake in the profits. I want to be known in Skyrim as the best smith/enchanter/alchemist around! An online marketplace would be cool too

Guess Im the only one

There will be a mod for that.

You played Recettear, I'm guessing =)

As the thieves guild master, I expect payment from you to operate or we'll wipe your store clean

That's exactly the kinda cool stuff I'm talking about, cutthroat competition, custom orders, expanding your store to more cities.

PS- I can't bring myself to turn in the skeleton key
