Commodore 64 was one of the most popular and best-selling home computers of the 80's. It had a vast library of games available in floppy disk and cassette tape formats. During the Great Video Game Crash of 1983, Commodore attempted to break into the market which had mostly been lost to Atari. Commodore also had an earlier system called the VIC-20. In the Dracula-themed episode, the Nerd is seen reviewing a game for the VIC-20 called The Count, which was made by Scott Adams who had programmed a series of "Adventure" games that involved mapping and typing as opposed to making a character fight.
