I wish Skyrim had....
A town you can bring back to life.
Basically some little town that has been empty for years and through quests and investing you build it back up. You pick what type of stores and other places are there. You can even pick what the guards look like if you decide to have any at all. That would be really awesome. At least then you you'd have something to spend money on. It would even be cool if you got to choose who lived there and how big it actually got.
