I didn't play the original but if I'm being objective as much as I love Xenoblade 2 it doesn't have the same broad apeal as Mario Oddessy or BOTW.
You'll love it if: You like a heavily story driven game in the Amine genre, don't mind some what complex (very layered) game mechanics that can be frustrating to get the hang of but are rewarding in the end, and aren't expecting a really interactive fighting experince ( the combat does require a lot of strategy but its not fully real time action like BOTW).
