I will not spoil you with the story, but killing dragons, becoming a vampire or werewolf is just a small sample of what you can really do in game. You can build a house, arrange it, pick up a lots of furniture for it and start decorating. But it's not really what the game is about. You will find the story really interesting, you should make choices, which will affect the story and the gameplay after that. Day and night cycles, cooking food, the crafting system is good.
Excellent choice!
