Lightning Returns: Final Fantasy XIII
Yep, theres going to be a 3rd Final Fantasy 13 game. Apparantly this one will be more interactive and dynamic than before and will fundamentally change the FF formula.
The armor you get for Lightning will be shown on her character and will affect her abilities and she can interact with the environment alot more. Theres also the odd mechanic of time, 'The world of Lightning Returns runs in real-time. When the game begins, the world, called Nobus (Novus?) Partus, is 13 days away from the end. She has 13 days and 13 nights to save humanity. The game runs on a doomsday clock, shades of The Legend of Zelda: Majora's Mask.' Does this mean that you have 13 days after starting the game to win? Thats going to be contraversial to say the least.
