Final fantasy 14? 15? 22? I stopped counting after number 10.
lol and I suck at roman numerals so it only makes it harder for me >_> Why cant they just make new names up?! LOL
Wasn’t the first going to be the developers final? Whatever his name was/is. The “Final” fantasy. Right. That went well.
Haha! Yeah me too. I know what 6 and 7 looks like, (played them to death) but yes. No. I don’t know. They should make them all like they used too! *banging pipe on desk. Breaks hip*
LOL!
Ah, more extensive than what I saw earlier, but along the same lines yes. =)
I saw this earlier, glad to finally get some screenshot and a bit of an idea of the story. Have you heard the outline of the basic plot?
Yep!
If you’re asking what it is, Wikipedia says: The story of the game takes place after Final Fantasy XIII and follows on from the -Episode i- novel which was released with the international version of Final Fantasy XIII.[2] Set a few years after Lightning and the others saved Cocoon, some survivors have decided to start over by rebuilding on Gran Pulse. Lightning, however, is nowhere to be found and thought dead by many, but Serah believes otherwise. When her town is suddenly overrun by monsters, a mysterious man named Noel appears to save her. Together, the two set off to find Lightning.[9]
Unlike Final Fantasy X-2, which had a more cheerful and humorous feel than Final Fantasy X, the overall tone of the story of Final Fantasy XIII-2 will be darker and more mysterious than the original.[2] Director Motomu Toriyama said that considering Vanille and Fang are gone and the world is in a state where Cocoon had fallen, there’s no way for the new story to be totally peaceful. Yoshinori Kitase, the producer, has said the story will have the serious feel of a true numbered entry in the Final Fantasy series.[2]
The actual story will delve deeper into the Fabula Nova Crystallis mythology and this time focus on the goddess Etro.[2] The game will once again feature Lightning as the protagonist.[2] The personality of Lightning will be the same as it was in the original game and not experience a change like Yuna had in Final Fantasy X-2. The game’s story will continue to value the refined and noble qualities of Lightning’s personality.[8] Other characters will also appear in the game but in new and unexpected forms and some of these returning characters will see major changes to their personality.[2] The game will also have a number of new characters, in addition to the mysterious man shown in the teaser trailer. The mystery man in the teaser trailer is in direct conflict with Lightning and equal to her in strength.[2] Lightning has a new mission this time, and as she attempts to fulfill this mission, she’ll end up in a confrontation with this mystery man.[8]
The original game ended with a lingering question: “Is Lightning really happy?” The conclusion of the story in Final Fantasy XIII-2 will provide a clear answer to this question.[8]
