I have been through the stages of missing skyrim now!
What I would love to know is, (this question is for developers or bethesda staff of Skyrim), what were the ideas you had for dlc? I would really like to know!!!
Why wouldn't they? I think he just wants to know what some of the possible DLC ideas were when they were thinking of them, NOT what they were working on and then scrapped, assuming this is what they did.
