I'd be a Fighter.

I mean, not to fall back on 8-bit, but I really do like swords.
In a Final Fantasy world, I'd want nothing more than to be able to wear cool armor, use heavy weapons, and fight monsters.
Rock on!

I wouldn't want to deal with all the worry of a magic user. The day I die'll be the day I get nuked before I sink my murderous Falchion edge into whatever pitiable object stands in my way.
