John Romero revealed on Nightdive Studios' Deep Dive podcast that Paul Neurath, founder of Looking Glass Studios, invited him to co-found the company, but he declined due to a prior commitment. Romero began his career at Origin Systems in 1987, where he initially worked on porting 2400 AD from the Apple 2 to the Commodore 64, but the project was canceled, leading him to collaborate with Neurath on Space Rogue.
