It's simply amazing. Though the game does reuse a lot of assets from BOTW, there is a lot of new stuff that wasn't in the previous game. The new map is absolutely huge and filled with explorables galore. I've played through BOTW three times and this sequel is still fresh as a daisy. Tears keeps you guessing and always presents more mysterious and exciting scenarios. You can easily become happily lost for hours. It's a familiar yet very different game, much like Majora's Mask was to Ocarina of Time.
Expect to see some classic monsters and items that were missing from the previous title. Much like Majora's Mask, Tears of the kingdom will be unforgettable sequel to an already legendary title. A must play for sure.
