The Definitive Version of Ratchet and Clank can be found on the Ratchet and Clank Collection on Playstation 3. One of the things that this updated version of the original game has to offer is the optional stereoscopic 3D support. While the graphics were not as updated as you might expect they stayed very true to the original, as opposed to the later releases, which look noticeably altered. The increased frame rate, and faithful story make the Playstation 3 release of Ratchet and Clank the best way to play and therefore it is the Definitive Version.
