I just want to mention that the main reason why Fiona's story was changed is that Ker deeply regreted not making her a mandatory character earlier in the story. With her unique abilities she's too useful.
Most of the changes to existing characters are only meant to make them mandatory.
True, that does make sense. I just have so much apprehension to changes to characters, story, the world. Remake was never finished and I felt like I never got closure to the story or the characters. I put 125 hours into playing that one game, I would have happily put another 125 hours in if it meant everything was completed. But now the game is being restarted again and I don't know how many years its going to take to get caught up. Just worried that story or characters interactions are going to be cut in order to make up lost time. As nice as the new engine is I would have been fine sticking with VX Ace if it meant seeing the game completed.
