At this time, Romero met another employee, John Carmack, who invented a way to create fluid screen scrolling on PC and created a demo that plagiarized Super Mario Bros. 3 titled Dangerous Dave in Copyright Infringement. All of them ended up working on a full demo of Mario 3 for PC and sent it to Nintendo. While Nintendo was impressed, they turned it down as they had no interest in putting their properties on anything but their own hardware at the time. Around this time, Scott Miller of Apogee software caught wind of these events and wanted to hire the group. He staged a guerilla recruitment process by sending several "fan" letters in rapid succession that the group discovered came from the same address. This was necessary because Softdisk screened all mail and his formal letters would have been thrown out. Romero, Hall, Carmack, and several other Softdisk employees ended up jumping ship to Apogee where they formally became id Software. They ended up developing several iconic franchises, including Commander Keen, Wolfenstein 3-D, Doom, and Quake.

This resulted in Romero and other staff members leaving the company around the same time. Still, the remaining members marched on and continued to make a steady output.
