In 1991, John Romero and his team at id Software, after releasing Catacomb 3-D, a groundbreaking first-person shooter, realized the future of gaming. Despite starting work on another 2D game, Romero quickly recognized that the future was in improving upon what they had achieved with Catacomb 3-D. The team decided to shift their focus to developing Wolfenstein 3D, embracing speed as a critical factor in differentiating themselves from other games of the time. Their development process was unconventional by today's standards, with a lack of detailed design documents and version control systems. Romero's vision and commitment to speed and gameplay set id Software apart, leading to the creation of revolutionary games that changed the course of the industry.
