Final Fantasy II. The mechanics are a complete mindfuck but once you learn how magic penalties from equipment and weapons work (everything gives magic penalties so it's best to have your casters running around naked for most of the game) it ends up playing like all the other NES Final Fantasies with a lot more customization.

I just wish the game itself actually told you any of the shit you need to know in order to play it, since there's no way to figure out most of its systems without a guide. I still have no fucking idea how to increase Agility or Evasion rate, and when half your team embraces the traditional Celtic battle uniform that shit is kind of important to have.
