One thing I do notice, watching through the FFVII LP is that the characterization of any character you don't bring along for the ride gets abandoned. Outside of scenes where they are mandatory characters (in their personal story) if you don't bring them along, they are left behind. Even when they're present, all they really do is comment on what's going on.

I hope the remake fleshes out the characters who aren't Cloud and Tifa better, in my opinion.
