John Carmack apologizes for pushing id Software too hard during Quake development on the game's 30th anniversary

Quake turned 30 on June 22, 2026, and the anniversary pulled some unusually candid reflections from the people who made it — including a blunt verdict from co-designer Sandy Petersen and a rare public apology from John Carmack.

Petersen opened the conversation on X, writing flatly that Quake ruined id Software. He praised the game itself — calling it an amazing feat of art, programming, and design — but said the workload broke the team spiritually. He then listed everyone who left id within a couple of years of shipping Quake: John Romero, Shawn Green, Dave Taylor, Mike Abrash, American McGee, and Petersen himself. His read on the exodus was simple: not a talent problem, just burnout. Petersen still called Quake absolutely worth the cost, describing it as an iconic titan of the gaming world, but added that id could have kept that dream team together with better management. His parting shot on id's post-Quake output: the only other truly great game the studio produced was Quake 3, and even that didn't reach the level of the pre-Quake games.

Carmack responded directly and didn't push back. He admitted Quake was overly ambitious technically, and argued the studio could have delivered all the great multiplayer and modding work inside a Doom++ engine — giving designers a stable base instead of pulling the rug out from under them multiple times. Then came the apology: I pushed everyone too hard. Carmack said he failed to understand that maturing companies need more slack, and that running people at startup intensity constantly will wear them out. He also acknowledged his own limits, noting he was working as hard as humanly possible and still missing his own goal points. He flagged the founders' original stock arrangement as another structural mistake — well-intentioned, designed to keep ownership with active contributors, but Silicon Valley-standard vesting would have worked out better. Carmack did defend the high bar set for Quake level designers, crediting Romero for establishing that standard early, though he said the team should have figured out how to pair artists and designers together sooner.

Notably, Romero — who is famous for gently but consistently correcting Petersen's recollections — largely stayed out of the disagreement this time. The 30th anniversary conversation landed as one of the more honest public post-mortems any of the id founders have given, and it arrived without any corporate filter: just two veterans on social media reckoning with what building one of the most important shooters ever actually cost them.
