Nomura says that he recently did a walkthrough of the full world map. He also did a check on the game's dungeons and the side paths in the game's towns. He was impressed with how expansive everything is.
When Square Enix announced the development of its "Luminous" next generation engine, some very cruel people joked that maybe Versus would be updated to use it. Actually, the game does use the lightning technology from Luminous, Nomura reveals. However, the game also uses a game specific engine that's specialized for action.
With Versus, Nomura promises a Final Fantasy like you've never seen before.
