Creating empathy for the Shades is so damn simple, yet extremely effective anyway. It's what I've been clamoring for more games to do. Show both sides. Create some real moral choices that way (ok, so Nier didn't really do the latter, but the setup's there). And while it does add another dimension to the proceedings, I wonder why they "hid" this in your first playthrough. I guess peeling away that layer during playthrough B (I consider C/D to mostly wrap up the Kaine and Tyrann subplot) was a conscious decision to create a relatively unique perception of the story, but I think I
personally would've preferred having everything wrapped in one go through.
The way it is, though, it's interesting to observe how people's reactions and impressions (I've read through many spoilered posts in this thread now
) changed before and after the second playthrough.
