Oh yeah, I did listen to that one. It was a perfect venue for Carmack because I could listen to John speak about anything for as long as John wants to speak about it. Rogan didn’t need to do much prompting for Carmack to spill his solid-gold guts, and he also didn’t feel the need to cut in.
It helped that Rogan is a self confessed Quake nut. If someone didn't have exposure to those early id software games, they might not have been as much at home with Carmack.
