I'm sure this has been debated elsewhere before, but when Kaede snaps in the anime it really gives her character a lot more believability as well as adding a whole other dimension to the story. So often we get these harem anime series where everyone is just peachy keen with each other despite the rivalries for the protagonist's heart. Kaede's sudden turn gave us a glimpse of something that simply felt more real.
Furthermore, gven that Sakura is confirmed for Essence+ I feel reasonably confident saying the following:
My personal opinion is if they do adapt some of the anime's story points to the game the game's story will only be better for it. If, however, Kaede is depicted more or less exactly as she was in the original game then it will relegate her once again to being the most boring character of the story, not to mention it will waste so much potential for dramatic and character development. Though again, the Japanese do seem to have a soft spot for doormat characters.
