Are You Looking for a Dark Emotional Story?
One of the things the original NieR was known the best for, was its dark and moody story. Automota is going to be very much the same experience, with a dramatic and character driven tale. You should be fully aware before going in, that Automata isn’t going to be an upbeat and cheerful experience. This isn’t to say that the entire game is depressing, just that NieR in general deals with dark and multi-faceted themes.
Just like the first game you’ll learn about both the bright and dark sides of humanity, with everything that falls in between. Just make sure you’re in the right head space for NieR: Automata, as you’ll, no doubt, be dealing with some heavy themes and events.
