I would like a few more unique locations and gameplay types, instead of all the quests taking place in the same narrow mine cave system with evenly distributed levelled enemies.

So I would like each dungeon to have a different feel with a different gameplay experince, not just combat: maybe a Tomb where you have to do some DaVinci Code puzzling or some physics based environmental traversal and more one-off combat encounters (like no enemies for all the dungeon, until the end when you awaken the sleeping dragon).
