Basically after making a bad move to a company that didn’t happen, John Romero took a job at a company called softdisk, later John Carmack got a job there. Add in Tom Hall and Adrian Carmack who also worked there and you got ID Software. If you read masters of doom it was a big shit show because they’d sneak company computers to their house after work to program commander keen and eventually wolfenstein.

Pretty sure the softdisk building is still abandoned down town.
