Some of the graphical changes made by Square Enix to later builds of Final Fantasy XIII are becoming clear when released screenshots are studied and compared by fans.
Two released screenshots are almost identical but are from different builds, giving fans an easy way to directly compare different versions of the game and look at changes made to the game engine. The question on the lips of many fans will be why these changes have been made - were they necessary changes for performance, or are they to accomodate the game's multiplatform status?
