The Final Fantasy series either ending or rebooting.
And by "rebooting" I mean doing something like the following:
Final Fantasy (I): [Insert Poetic Subtitle] - Normal "old school style" FF (set jobs, side view ATB battle, etc) where you play as [Insert Main Character Name Here].
Final Fantasy (II): [Insert Poetic Subtitle] - Strategy RPG (such as Tactics) where you play as [Insert Best Friend of FF's Main Character Name Here] that continues the prior story, but perhaps in a new location of the world. So say... if FF I: IPS took place in South [Insert Name], FF II: IPS takes place in North [Insert Name].
Final Fantasy (III): [Insert Poetic Subtitle] - Return to the same play style as FF I: IPS, now following the story of [Main Character] as they slowly descend into becoming a villain.
Final Fantasy (IV): [Insert Poetic Subtitle] - Now perhaps say... an ActionRPG (Kingdom Hearts if you will), that has [Best Friend] + [Wife of Main Character] seeking to stop the now evil [Main Character].
