Past 15 minutes..
I wanted to make this edit in my last post.
What I meant by FF magic spells not having specific accuracy damage and time, is that we don't know for instance, if Wakka just has to put out his hand and make ice appear and surround the enemy regardless of how fast and where the enemy is within two seconds while casting Blizzaga canonically speaking, and Firaga in FFX looks more like an explosion that suddenly appeared where the enemy is than flames, which is why spell damage is questionable.
I'm not saying this applies to all or many FF games but in FF7 and X at least, magic spells were not demonstrated in cutscenes as far as I know, but that means nothing other than what I've said. FF magic still pwns though.
