Fighting all the WEAPON in VII as the last boss, one by one o.O
Diamond was easy, just had to keep health up. Ultimate was hard in Mideel, as chances are, you would have one severely underleveled character, but the optional ones are easy. Sapphire got owned.Now, imagine having to fight Emerald and Ruby as last bosses...that would drive me to madness.

FF always needs that "Extra challenge", to give those that are willing, something more.
