I'm actually in the middle of doing a lot of things, but I had to post this here!

QUAKE IS THE BEST MAGIC EVER. Er, Materia. I don't know about other games, other FF - I didn't use it much. However, in Zack's playthrough in Crisis Core? Real-time battles where you don't want to get too close to the enemy?

QUAKE.
QUAKE.
QUAAAAAAAAAAAAAKE.
