In late 1991, id Software had just shipped five Commander Keen games in six months and was working with 16-color EGA graphics and early Sound Blaster audio.
Facing burnout after multiple Commander Keen titles, the team decided to create a new 3D game, with Romero suggesting a modern remake of the 1981 classic Castle Wolfenstein.
The project began using the 16-color EGA engine from Catacomb 3D, but a crucial suggestion from publisher Scott Miller prompted a switch to 256-color VGA for a cleaner look.
John Carmack built the VGA renderer using a 2D matrix for level data, which allowed the team to adapt their existing 2D editor, Ted 5, for creating 3D levels.
Initial plans to replicate the original game's stealth mechanics were scrapped after playtesting revealed that fast-paced running and gunning was the most enjoyable part of the experience.
After a promising visit to Sierra Online, the team received a $2.5 million stock acquisition offer from Ken Williams but the deal fell through when he rejected their counteroffer for $100,000 in cash.
To avoid activating all enemies at once, the team implemented "sound zones" using floor tile data, allowing gunfire to alert only enemies in connected areas and creating suspense.
After hiring artist Kevin Cloud, the team made a spontaneous late-night decision to abandon their new Madison leases and relocate the entire company to Dallas, Texas.
To add mystery, the team convinced a reluctant John Carmack to implement "push walls" for secret areas, while new hire Jay Wilber successfully located and purchased the Wolfenstein trademark for $5,000.
Composer Bobby Prince flew in and set up a studio in the office to create the game's music and record all the iconic enemy voice effects, which were performed by the development team.
Publisher Scott Miller proposed releasing the first episode as shareware to take pre-orders and created a brilliant pricing model that incentivized players to buy a six-episode bundle with a hint book.
After creating a fake "PC-13" rating screen, Romero had to quickly code a custom multi-disk installer, leading to the game's official shareware release at 4 AM on May 5, 1992.
The team crunched to finish the remaining 50 levels after the shareware's massive success and inadvertently created the concept of speedrunning by publishing their fastest level times in the hint manual.
Romero shares his admiration for Unreal Engine and reveals that the iconic Cacodemon death sound from Doom originated from a commercial sound effects library.
Romero explains their fast QA process was based on highly iterative coding and testing from their 80s assembly days, and confirms that they worked nearly all waking hours during development.
Romero discusses their approach to piracy, which was to ignore it and never use copy protection, instead focusing on fostering a community by releasing game source code early.
