id Software's second FPS only brought in $5,000, and the studio might not have made Wolfenstein and Doom if the game hadn't made a dev fall out of his chair: 'That was just one of the craziest things in a videogame I'd ever seen'

In celebration of the 35th anniversary of Doom developer id Software's founding, co-founder John Romero has released a video retrospective on one of id's most unsung games: Catacomb 3-D.

The video featured Romero's own recollections, as well as those of id vets Tom Hall, John Carmack, and Adrian Carmack⁠—no relation on those last two, by the way. I only found that out embarrassingly recently.

id began work on Catacomb 3-D in October 1991, after completing Commander Keen in Aliens Ate My Babysitter⁠.
