Crystal Castles is a legendary arcade maze game developed and published by Atari, Inc. in 1983. What made the game so good were: the trackball and jump button controls (which gave a good degree of freedom to make headway at pace) and the unusual isometric graphics (which drew on-screen in an unusual and interesting way).
Taito‘s Bubble Bobble first came out in arcades in 1986. Its colourful, jolly, platform action proved a sensation among gamers, and it has since gone on to earn “legendary” status in the retro gaming community.
