Definitely a hybrid.
You can use your Power to open up areas before any story based objectives are there, you're encouraged to explore and do as much in each locale as you can to strengthen the Inquisition.
So you can treat it like a slightly more locked-down Skyrim, or you can just follow the primary Inquisitor questlines to advance the story and get your traditional RPG on.
The question is, how successful is this hybrid formula?
