I didn't really care about the story's deficiencies in XY, and I liked to actually feel appreciated this time around. And now that I've experienced the parade, I can't really live without it anymore. After playing XY, it was quite anti-climatic seeing BW's ending (Wait, so we go straight into the credits? That's it?), and that's even when I consider that Unova's story does not end there and continues into BW2. I could possibly live without a celebration with RBY and GSC, because it was just Team Rocket, but not for other villains/legendaries which were much bigger threats.
