just to make things clear, 2B 9S and YorHa are Androids, fighting against enemies - Machines. Its a huge difference in this game, I mean I wouldn't put them all into one bag which is "robots" :D

may even be humans

its been already said after beating prologue, that humans are hiding on moon, because Aliens created machines to wipe the humans from earth, and Bunker is just in the space, its not directly on the moon.

How do you enjoy music so far? I think its amazing that Keiichi Okabe made a gibberish (fake) language, especially for NieR games. I still listen to NieR music even tho I finished all nier games long time ago.Some of those songs are so powerfull and some gives me amazing chill time. I definitely couldn't find such an amazing soundtracks in any other games. Its just next level imo
