For Quake's 30th anniversary, John Carmack responded to former id colleague Sandy Petersen's claim that Quake "ruined id Software" by addressing faults in studio organization. Petersen argued the game forced staff to work too hard, which "broke [id Software] spiritually." Carmack agreed with Petersen's point about the crunch on the game and discussed "overly ambitious design" and other factors that contributed to id's issues during Quake's development. Both Carmack and Petersen shared a mutual understanding of no hard feelings in the end.
