cemented. In a post-credits scene, Qwark advertises his "Personal Hygienator", much to Ratchet and Clank's disgust and discomfort, and Clank turns off the Holovision (TV) ending the game. Development and release After finishing work on the Spyro the Dragon series on the PlayStation, Insomniac originally intended to launch a game codenamed I5 (Insomniac game #5) for the PlayStation 2. The developers, however, were never enthusiastic about it, and the idea was dropped after six months. Ratchet & Clank was based on an idea by Brian Hastings, which would feature a space-traveling reptile alien who would collect various weapons as he progressed through the game; Ratchet's final form was decided upon after Insomniac considered a space lizard with a tail and various terrestrial creatures, including dogs and rats; feline features stood out to the developers because of the associated sense of agility. Another early idea was to have three small robots attached to Ratchet, which would perform different functions. However, Insomniac realized that having the robots was both complicated and created confusion about Ratchet's appearance, leading them to have only one robot, Clank. According to an interview, not much was cut but that (according to Insomniac) "Interestingly, we really didn't cut anything except for a few weapons and gadgets that just weren't fun when we prototyped them. There was the Revolverator – a drill gun which would spin enemies around once Ratchet impaled them and the Mackerel 1000 – basically a fish that took the place of the wrench. Both of these got cut because they were either too hard to use or just didn't add anything to the game." Shortly after changing the game from I5 to Ratchet & Clank, Naughty Dog asked Insomniac if they would be interested in sharing the game technology used in Naughty Dog's Jak and Daxter: The Precursor Legacy, asking that Insomniac in turn share with them any improvements that were made. Insomniac agreed, resulting in most of the Ratchet & Clank engine technology being developed in-house by Insomniac, but some important renderers were developed by Naughty Dog. Looking back on the agreement, Ted Price said that "Naughty Dog's generosity gave us a huge leg up and allowed us to draw the enormous vistas in the game." Some years later, Ted Price clarified Insomniac's stance on engine technology while obliquely mentioning the shared renderers: Pre-production of the game began in late March 2001, with a
