In 1993, Dan Linton, owner of a hugely successful BBS called Software Creations, visited Texas and made his way to id Software. This is the footage he recorded one night in November 1993. Shown are several of id's employees at the time: Jay Wilbur, Shawn Green, John Romero, Dave Taylor, Sandy Petersen and Adrian Carmack. Bobby Prince was visiting to finish the music and create the sound effects. This video has 21 minutes of DOOM before the sound effects were put in as well as some early deathmatching with Shawn Green.
