Final Fantasy is a series of games. There are a LOT of them but each one of them is NOT a sequel from each other. They're all different. The only sequel that I know of is Final Fantasy X-2, that was made because of the prequel's popularity and sad ending, and the upcoming movie Final Fantasy Advent's Children, which is a movie sequel to the Final Fantasy VII Playstation 2 game which I've never played in my life so I'd appreciate it if you didn't ask me about it and follow the instructions of the picture below.
