Sephiroth (da da da daaaa) - Very in depth post! You kind of make me want to play Drakengard 3 and the original NieR at some point when I finish these other play throughs so I can appreciate the full story. Are the first two Drakengards not relevant?

Edge - You're not the only one to say that about good stuff coming. KK mentioned above that the events on the second and third play throughs are "significant", and also when I went on the N4G PS4 community earlier saying that I completed my first run someone replied "the best is yet to come!" I'm assuming that we will see more of (SPOILER)A2 because after the fight with her I was expecting her to show up again but she never did.
