In an interview with Famitsu, Square Enix's Tetsuya Nomura revealed new information about Final Fantasy Versus XIII.
According to Nomura, many of the rendering and shading tools used in the development of FF Versus XIII were used to polish Final Fantasy VII: Advent Children Complete. The film's team wanted to use more advanced techniques and tools than those available when the film was first produced, and Versus XIII's tech met the team's standards. Now this may be a stretch, but it's as if Nomura is hinting that the quality of visuals behind Final Fantasy Versus XIII may come close to replicating certain aspects of Final Fantasy VII: Advent Children.
Nomura also stated that Roen, the company behind the character costume designs for Versus XIII, has completed work on the costumes of the main character and his allies. Apparently, recreating the clothing designs in the game was difficult due to the extreme detail required.
Hopefully we'll see more of Versus XIII along with FFXIII and Agito XIII at this year's E3.
