Replaying the game currently I can say outside graphics, the other additions I think the game pretty much needs is an improvement on the script. A lot of what people say is random, or something that encourages more discussion....that everyone ignores and completely drops. The dialogue in the game in general is pretty shaky at times and just feels very awkward, now I'm not one for normal everyday dialogue in a game, but reading through the dialogue in this game makes it feel so weird. So I propose a good change to make it flow a lot better and make people talk about relevant stuff instead of swapping topics for a single sentence and dropping the topic completely.

I also wouldn't mind for a little more expanded interaction with some party members, a lot of them tend to just drop into obscurity after their little story quest, for example Red XIII, after Cosmos Canyon it feels like he could have been removed completely and the game would play out the same way. So in terms of new content I would love to see more back story or character interactions with party mmbers to make them feel like they really belong in the group, even in disc 3.
