they made final fantasy I-XI, tactics, anthologies, chronicles, mystic quest, tactics 2,and FFX-2. they started on making a FFVII for the N64, but decided not to. rumor has it that they are currently trying to figure out a way to make a FFVII-2, they want to come up with a story that you would want to share the same name and characters with. they are also planning on releasing final fantasy 1 and 2 as remakes on the psx, along with a game for the gamecube/gba dubbed final fantasy: crystal chronicles.
