Final Fantasy XIII
Final Fantasy Agito XIII
Final Fantasy Versus XIII

These were supposed to be three seperate 'XIII' games with the same mythos. Well, they made a sequel to XIII......it was, well you know what it was. Now XIII-3 Lightning Returns! Ohh look our first Fianl Fantasy Trilogy. Wait, didn't we already have a trilogy sort of thing with the Fabula Nova Crystallis thing? Not a connected trilogy but basically a non related trilogy? Ok.

Final Fantasy Agito XIII, now Type -0 - Ok now things are really getting screwed up. Oh wait there's more, Type - 0 has its own trilogy sub series too right? OK.

Final Fantasy Versus 13.....now FF 15 with sequels already in the make.

Why didnt they just say, ok people FF XIII will be a trilogy, FF 15 will be a trilogy, FF type 0 will be a trilogy. that wpuld have saved a lot of years of complete bulltrout. Anyone agree???
