Alfonso John Romero (born October 28, 1967) is an American and Irish video game developer. He co-founded id Software and designed their early games, including Wolfenstein 3D (1992), Doom (1993), Doom II (1994), Hexen (1995) and Quake (1996). His designs and development tools, along with programming techniques developed by the id programmer John Carmack, popularized the first-person shooter (FPS) genre. Romero is also credited with coining the multiplayer term "deathmatch".
Following disputes with Carmack, Romero was fired from id in 1996. He co-founded a new studio, Ion Storm, and directed the FPS Daikatana (2000), which was a critical and commercial failure. Romero departed Ion Storm in 2001. In July 2001, he and another former id employee, Tom Hall, founded Monkeystone Games to develop games for mobile devices.
In 2003, Romero joined Midway Games as the project lead on Gauntlet: Seven Sorrows (2005), and left shortly before its release. He founded another company, Gazillion Entertainment, in 2005. In 2016, Romero and another former id employee, Adrian Carmack, announced a new FPS, Blackroom, but it was cancelled after failing to find a publisher.
Alfonso John Romero was born on October 28, 1967, six weeks premature, in Colorado Springs, Colorado. He has said that he has Mexican, Yaqui, and Cherokee grandparents. His mother, Ginny, met Alfonso Antonio Romero when they were teenagers in Tucson, Arizona. Alfonso, a first-generation Mexican American, was a maintenance man at an air force base, spending his days fixing air conditioners and heating systems. After Alfonso and Ginny married, they headed in a 1948 Chrysler with three hundred dollars to Colorado, hoping their interracial relationship would thrive in more tolerant surroundings.
Among Romero's early influences, the arcade video game Space Invaders (1978), with its "shoot the alien" gameplay, introduced him to video games. Namco's maze chase arcade game Pac-Man (1980) had the biggest influence on his career, as it was the first game that got him "thinking about game design." Nasir Gebelli (Sirius Software, Squaresoft) was his favorite programmer and a major inspiration, with Gebelli's fast 3D programming work for Apple II games, such as the shooters Horizon V (1981) and Zenith (1982), influencing Romero's later work at id Software. Other influences include programmer Bill Budge, Shigeru Miyamoto's Super Mario games, and the fighting games Street Fighter II, Fatal Fury, Art of Fighting and Virtua Fighter.
John Romero started programming games on an Apple II he got in 1980. The first game he wrote was an unpublished clone of the arcade game Crazy Climber. His first published game, Scout Search, appeared as a type-in program in the June 1984 issue of Apple II magazine inCider. At least 12 of his games published for print and disk magazines were developed under the name Capitol Ideas Software. He entered a programming contest in A+ magazine during its first year of publishing with his game Cavern Crusader. The first game Romero created that was eventually published was Jumpster in UpTime. Jumpster was created in 1983 and published in 1987, making Jumpster his earliest created, then published, game.
Romero's first industry job was at Origin Systems in 1987 after programming games for eight years. He worked on the Apple II to Commodore 64 port of 2400 A.D., which was eventually scrapped due to slow sales of the Apple II version. Romero then moved onto Space Rogue, a game by Paul Neurath. During this time, Romero was asked if he would be interested in joining Paul's soon-to-start company Blue Sky Productions, eventually renamed Looking Glass Technologies. Instead, Romero left Origin Systems to co-found a game company named Inside Out Software, where he ported Might & Magic II from the Apple II to the Commodore 64. He had almost finished the Commodore 64 to Apple II port of Tower Toppler, but Epyx unexpectedly cancelled all its ports industrywide due to their tremendous investment in the first round of games for the upcoming Atari Lynx. During this short time, Romero did the artwork for the Apple IIGS version of Dark Castle, a port from the Macintosh. During this time, John and his friend Lane Roathe co-founded a company named Ideas from the Deep and wrote versions of a game called Zappa Roidz for the Apple II, PC and Apple IIGS. Their last collaboration was an Apple II disk operating system (InfoDOS) for Infocom's games Zork Zero, Arthur, Shogun and Journey.
1990s: id Software and first-person shooters
Romero moved to Shreveport, Louisiana, in March 1989 and joined Softdisk as a programmer in its Special Projects division. After several months of helping the PC monthly disk magazine Big Blue Disk, he officially moved into the department until he started a PC games division in July 1990 named Gamer's Edge (originally titled PCRcade). Romero hired John Carmack into the department from his freelancing in Kansas City, moved Adrian Carmack (no relation) into the division from Softdisk's art department, and persuaded Tom Hall to come in at night and help with game design. Romero and the others left Softdisk in February 1991 to form id Software.
Romero worked at id Software from its inception in 1991 until 1996. He was involved in the creation of several milestone games, including Commander Keen, Wolfenstein 3D, Doom, Doom II: Hell on Earth and Quake. He served as executive producer (and game designer) on Heretic and Hexen. He designed most of the first episode of Doom, a quarter of the levels in Quake, and half the levels in Commander Keen and Wolfenstein 3D: Spear of Destiny. He wrote many of the tools used at id Software to create their games, including DoomEd (level editor), QuakeEd (level editor), DM (for deathmatch launching), DWANGO client (to connect the game to DWANGO's servers), TED5 (level editor for the Commander Keen series, Wolfenstein 3D: Spear of Destiny), IGRAB (for grabbing assets and putting them in WAD files), the installers for all the games up to and including Quake, the SETUP program used to configure the games, and several others. In his keynote speech at WeAreDevelopers Conference 2017, Romero named this period Turbo Mode, in which he emphasizes having created 28 games, in 5.5 years with a team consisting of fewer than 10 developers. Romero is also credited with coining the multiplayer term "deathmatch".
In level 30 of Doom II, "Icon of Sin", the boss is supposed to be a giant demon head with a fragment missing from its forehead. When first viewing the demon, a distorted and demonic message is played, which is actually John Romero saying "To win the game, you must kill me, John Romero!", reversed and distorted to sound like a demonic chant. One can use the "noclip" cheat to enter the boss and see Romero's severed head which is skewered on a post. The player defeats the boss (without the noclip cheat) by shooting rockets into its exposed brain after activating a lift and riding it. Romero's head functions as its hit detection point; when he "dies", the boss is killed and the game is finished. In the 2013 IGN Doom playthrough to celebrate Doom's 20th anniversary, Romero shared the backstory behind the inclusion of his head as the final boss and the reversed sound effect – they were both a result of in-joke pranking between development team members.
During the production of Quake, Romero clashed with John Carmack over the future direction of id. Romero wanted the game to follow his demanding vision without compromise, but Carmack insisted that the project had to make steady progress toward completion and accused Romero of not working as much as the other developers. Although Romero relented on his vision and joined a months-long crunch effort to finish the game, this did not resolve the tensions within the company, and Romero was forced to resign. In a 1997 interview, Romero said, "Leaving after finishing Quake was the right choice — leaving after finishing a hit game. I keep on good terms with the id guys and it was pretty easy because we've been friends for years." In 2022, during a conversation with podcaster Lex Fridman, Carmack stated that, in hindsight, he regrets the way he dealt with the firing of Romero, citing immaturity and lack of understanding of corporate structure as the primary causal factors. Additionally, Carmack clarified that both he and Romero were currently on good terms.
