As I've stated previously, from the very beginning, the Shrines felt like a turtorial. I feel like I learned a new trick to interact with the environment in a different way in each of them. A great feeling, but a build up that never became of any real use other than solving some minor puzzle tucked away in some corner of the world. There was no ultimate puzzle that incorporates everything you've learned in a different way, like the way a dungeon would work. Even the beasts just felt like a multi room shrine. The only real interesting part was how you entered the beast. This game was puzzle after puzzle, like any Zelda, with perhaps more total puzzles than any other Zelda game, but the Shrines (same environment, same music, same enemies, same textures, same rules) made them dull.
I really hope the expansion has something unexpected to give us. We know it's a completely new story, but I find it hard to imagine that's all there is. With the size of the world they created, I can imagine there's far more hidden things than first sight would reveal. There could very well be full dungeons hidden beneath the surface. I'd like to imagine the game we've played so far is just the tip of the iceburg. The three pendent quest from LTTP, if you will, and the 2nd half of the game has yet to be played.
