Gets the important things right - it's worldbuilding, characters, and tone are all exceptional, and it makes the otherwise (at least right now) standard anime-esqe story work. There is a likability to the world, and the level of detail that goes into every aspect of it's universe is impressive. It feels alive in every sense and filled with history.

Solid RPG mechanics too. Endgame is messy but when it's this solid in terms of gameplay it's hard to complain. And while the gatcha mechanics won't be for everybody, they aren't required to enjoy the world and story. Addictive stuff - I can't wait for more.
