hahaha, I think it's pretty safe to say FFXIII-2 wins this poll. It gets my vote, I liked the first game but the second one was a serious fuck up if you ask me, it was the start of that story getting ruined, followed by the final nail in the coffin that is Lightning Returns.
That game sounds really daft. It have to be either 10 2 ff 1or2 or grimoire of the rift.I would have to say Mystic quest. The whole thing was terrible, i couldnt understand how it was even allowed to be released. no save points, no party, a main protagonist named Benjamin(real original Final Fantasy sounding name). really terrible.
