"I largely recant from that now." On Rage 6-year development time he says: "I think we should have done whatever it would have taken to ship it 2 years earlier". Carmack also reflected on the internal development of Quake in this regard and described it as "traumatic" and says id Software could have split the game into two parts and shipped it earlier. Carmack supported the 2012 presidential campaign of Libertarian Ron Paul. Carmack is an atheist. During a conversation with Joe Rogan, Carmack revealed that he had trained in Brazilian Jiu Jitsu and Judo for several years as a hobby. During his time at id Software, a medium pepperoni pizza would arrive for Carmack from Domino's Pizza almost every day, carried by the same delivery person for more than 15 years. Carmack had been such a regular customer that they continued to charge him 1995 prices. On occasion he has commended the efforts of similarly focused programmers – first Ken Silverman, who wrote the Build engine for 3D Realms, and later with Tim Sweeney of Epic Games, who wrote the Unreal Engine.
