I couldn't believe what I saw in the first episode. This is one of the most faithful video game adaptations I've seen, and one that most manages to capture the essence of the game. It even has the same soundtrack.
Nier: Automata is one of the best games of the last generation and it deserved a quality anime like this. The animation is very well done, and although for someone who played the game the story doesn't feel very new, it brings a lot of nostalgia to see iconic scenes depicted in the anime.
Let's hope that the anime maintains the same quality in each chapter, since its debut has been impressive. Personally, I am very curious to see how they handle the development of the story with the multiple endings that the game had.
