Yoko Taro is such a troll. First acting as if A2 didn't come back, only to then show the obscure Accord (assumedly) with A2.
This season has been amazing. I absolutely loved it. It's hard to speak of it on its own, since I love the game, but I think I view it as an additional route of the game. It adds and changes details here and there in a meaningful way, similar to the different routes in the NieR games (particularly Replicant). I loved seeing the slight differences and some not so slight.
I also think this is the most straightforward version of the story we've gotten.
Compared to season 1 it's a massive improvement too. Better story execution, better animation, better action.
