Wonderful, superb, outstanding. This game is so good that it would be faster to list my few issues than to state everything great about it, those being the first few hours of the game can feel a bit rocky and that occasionally, the rushed nature of the game shows its head in the places where content was obviously cut (like what would have been the water dungeon.)
Exploration is sublime, on par with BotW imo. Sailing the ocean to fill out your map and discover new islands is just such an incredible feeling. Dungeons are good- far from the series peak in that department, but still good. Story is fantastic. Visuals are charming. I cried at the end. Buy a Wii U just to play this game. I'm serious.
