Yeah, a part of me wished that the God-generals would stay alive, and hell, there could literally be a spin-off game with them! That would of been amazing! However, I guess things were meant to be. Truth be told, the God-Generals didn't really seem that evil to me. They were just people who had their own reasons of following Van, because of their hatred of score, and, well, their ideals just ended up different from Luke n' friends. And Asch's, sort of.
I'll get back to Symphonia soon! I actually planned to play the Tales games in sequence (well, aside from Tales of Tempest, because god -- I don't want to).
