More than just an optimization/tweaking of Breath of the Wild, it really is a pretty different, yet no less magical game. For all the changes made (story, overworld, dungeons, bosses, etc.), the really revolutionary stuff comes from the ultrahand and fuse systems and how the physics really react realistically to whatever Ultrahand monstrosities have been created by Link. Even being able to dive down from the Sky to Hyrule to the Depths in one fluid motion is some Nintendo witchcraft. A game we'll be dissecting and experimenting with for years to come, just like Breath of the Wild
