Er...what's wrong with Sepiroth?
Materia system was good idea, that had mediocre realization. Nevertheless pairing all with something was always good idea :P
Yuffie? You couldn't catch her or...?
I found him boring. Don't really see the appeal in him.
I guess it's just me but I really didn't like the materia system after some point.
Oh I got her...I just wished I left her. She's really just there in the game and doesn't contribute that much of anything. She just sits there in the background with your other characters, hell she just wastes your time throughout the game.
I guess those are trivial complaints coming from me but I really found the game boring after disk one.
