"Dragon's Lair is a series of arcade games which were later ported to many different platforms including Laserdisk, Commodore 64, Amiga, and DVD's allowing for playing the game on home DVD players or XBOX/Playstation platforms.
When first released the game's enormous contrast with other arcade games of the time created a sensation when it appeared, and was played so heavily that many machines often broke due to the strain of overuse. It was also arguably the most successful game on this medium and is aggressively sought after by collectors."
