Don't know about anyone else, but the materia system beats any customize system in any other rpg I've played. Grids in FFX and XII meh. Seem more like a downgrade of the materia system to me even though you can potentialy get every spell and what not on one char. But 16 slots for materia is more then enough anyways. With a system like that of FFVII you can use any char you want at any given time and if you're forced to use a char you normaly don't use you only have to worry about the level of said char and not gain points and what not to get them usefull skill. Since the progress is saved to a particular item you can just transfer it and be done with it. Yes I know with the grid you can still get points for out of party chars but the chars start at different areas and it could take more points to get to a particular part of the grid to give them what you want them to have. I also get the whole uniqueness thing in battle but I rather use chars I prefer for storylines then battle.
Crap, I had something else I wanted to talk about but I can't remember what it is. Oh well. If I remember later I can just post it then.
