Well thought out sequel or cash-in brand recognition sequel? --- Legend of Zelda: Majora's Awakening of the Skyward Oracle Ocarina Princess Waker's Phantom Spirit Adventure to the Past coming to Super Wiicubeboy Advance 64
I really don't think this is a cash in sequel. I think Square really has a lot of faith in the world and characters they created for FFXIII, and want to prove it's potential for greatness to those in the fanbase that were skeptical, unsure, or indifferent with their feelings for this incarnation of Final Fantasy.
It was said that so much effort went into programming and designing that the developers did not get to explore the world and characters that they created as much as they would have liked.
