Now you have the chance to do it again, do it great, and take all of my money. Seriously. All of it. Drop down an expansion pack that fleshes out lycanthropy and vampires and cults, or multiple DLCs that accomplish the same thing. I will buy them. No questions will be asked. As they stand right now, vampirism and lycanthropy are both good starts, but shallow. The different vampire subtypes from Morrowind are absent, along with any quests pertaining to being all bloodsvcky. Waking up a vampire in one of the major vampiric houses is fertile fodder for an entire expansion pack by itself. What quests exist for werewolves are all very side questy and not getting much limelight, and wolfing out often makes the dovahkin weaker rather than stronger. The thieves' guild and dark brotherhood are both pretty good as-is, but the stealth mechanics could use some sprucing up. Working for daedra provides some great quests, but their one-shot nature could be made into something much bigger with an organized group of witch covens and cultists and undead kings to make friends with or set on fire. (And the opportunity to reuse the daedric temple architecture from Morrowind would be great, I loved the look of them!)
So in short, when you guys are sitting around a table talking about what to do to make a big pile of money, remember this. Skyrim is admirably covering the playstyle of someone who wants to stride out and hit a dragon over the head with a sword. It now just needs to flesh things out more for the people who want to do the shadowy and less-heroic deeds. The darker dungeons and improved stealth gameplay from your jam video show fantastic promise, but sneaking in the deepest darkness is only rewarding when there's something terrible to find down there, either to fight or to join.
