It's okay. It's got plenty of problems.
One of the most glaring being the obvious DLC teasers where a character leaves your party and something happens that you just don't get to see, even though it's apparently quite important.
I played it earlier today. I liked it, but it felt a lot different from the original Nier.
While the original wasn't great from a gameplay perspective, it had great atmosphere, and I don't know if Automata will live up to that based on the demo.
