So far it seems all the dlc and patches given to us seem to have came straight from or were inspired from features from Gamejam, but what direction do you think Bethesda would have taken in terms of DLC if they never did the Gamejam in the first place? Would they have opened with vampires? Would they have given us housing add-ons? Would it have been worse in your opinion, starting DLC ideas from scratch, or better?

What do you guys think?

Without a doubt in my mind, we got Dawnguard solely because a dev liked Underworld.

Would be dramatically different without it, perhaps in a good way.

Isn't Underworld about Vampires vs Werewolves?

Eeyup.
