If you have a Wii U or Switch, it's definitely worth the money. Is it worth buying a system solely for this one game? Hard to advise from that perspective. I'm having a blast, though. There's a ton of creative things you can do and ways to approach things. It's fun being able to climb almost anything just to wander around and it's easy to go to one place only to wind up seeing something in the distance and head there just to see what it is.
