Good review. I would like some more interiors as well like Hyrule castle and the Forgotten temple. Unfortunately I went way late to Hyrule castle (100+ hours in) and it was a cakewalk by then. I wandered in from the back side, paraglided practically straight into the dining hall without any trouble and explored from there. (Wasn't planned, was on the bay back from the Tabantha tundra. It was still an awesome place to explore although I did it backwards. Climbing to the top while avoiding the tracking beams was a lot of fun.
Currently I'm at 135 hours, 3.5 zones left to explore, 2 more dungeons (just finally got to the Zora domain) 28 more shrines to find, and it's still awesome. Yet after defeating Gannon (which will certainly be anti climatic) I doubt I'll ever start it over. The fun is in exploring, to see what's over the next hill. That doesn't really lend to repeat gameplay.
