Ironically Wolfenstein 3D, a title widely thought to have later popularized the first-person shooter genre, featured a secret level based on Pac-Man and early in its development designer Tom Hall had suggested a name along the lines of "3-Demon" before id Software decided to do a semi-remake of the once popular Apple II game Castle Wolfenstein.
