A fun character creator, otherwise it's generally unremarkable in terms of story, characters, and gameplay feel. Probably the most fun if you're playing with friends and just goofing off with creations. Beyond that, it's generally kind of dry, kind of generic.
I guess you can play as 2b from Nier:Automata, Geralt from The Witcher, and Noctis from FFXV, if you're into that kind of thing.
