In the end, Quake’s levels were divided among the four designers: • American/Tim co-created: 1 level • Sandy Petersen: 7 levels • American McGee: 9 levels • Tim Willits: 10 levels • John Romero: 11 levels It’s a tremendous credit to the entire team that Quake was as great as it was, particularly given that it was redesigned from an action RPG to an FPS with just seven months to go.
