I'm not doing any kind of official replay, but I've been slowly wading through a playthrough of FFVIII using only magic. I'm not a fan of intense challenges, but I thought this would be fun since the game usually keeps players from ever using the different spells, which have some very impressive cinematics. And there's an interesting balance between using strong spells versus keeping them for stats. And also switching it up a bit, Selphie, Quistis and Rinoa are gonna be my powerhouse characters, having magic-based limit breaks.
