Favorite learning system.

FFVIII's Junction System wasn't complicated, it just took all the fun out of battles. Well, for me anyway, 'cause I never used magic so my stats wouldn't go down, and I rarely used GFs so my rank wouldn't go down. So, I was basically limited to normal attacks, limit breaks, and special abilities like Doom, Recover, etc...

Materia was good, but I like FFVI. Everyone can learn every spell, but on top of that they each have their own abilities that can be developed in their own ways.
