Ghosts'n Goblins is a classic Capcom platformer that is invariably described as "ghoulishly difficult" by game reviewers. Ghosts'n Goblins was faithfully ported to the Nintendo Entertainment System, which is where many gamers first encountered Demon World. Capcom opted not to give home players any kind of break, making the NES version of Ghosts'n Goblins just as insanely difficult as its arcade inspiration. A port of the game also came out for Commodore 64, ensuring that most gamers of the 8-bit era got to experience it. In 2000, the game was ported to the Game Boy Color.
Spy Hunter is the original assault driving game, a vertical shooter with a steering wheel and gas pedal. Quality ports of the original Spy Hunter made it to the Atari 2600, Commodore 64, ColecoVision, and NES. An emulated version of the game was included in Midway Collection 2 on the PC and Playstation. More recently, a pedal-to-the-metal 3D update of Spy Hunter was released on the Playstation 2, getting that immortal bass line stuck in the heads of a whole new generation of gamers.
Both games have been immortalized in the hall of fame and found new homes on the Playstation 2.
