Heathfire was my first bought DLC.^^
I have already Severin Manor in Raven Rock.^^
But usually i buy and build houses everywhere in Skyrim, need place for my tons of books and dragon bones and tons of other stuff because i'm a messie girl, I COLLECT EVERYTHING.^^
Dragon riding is very useful, as i'm usually always overload.
But yes, i would like to travel with the dragon through Skyrim manually not in quick travel.^^
Edit: And yes, Skyrim could have more hard choices, especially in character specialization.
But still a very good RPG.
