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.
