Such simple graphics that its amusing!
World Karate Championship (1989) must have taken itself pretty darn seriously when it was first released, as it is after all a game that was at the pinnacle of what 1985 could muster; but, the waging of fights in monochrome fields, which don't shy away from using pink (magenta, actually) as the basic color around which the rest of the game chooses the palette can be quite amusing. Not to talk about the so very simple animations, the often finicky collision detection system and the very small number of moves. But, for what was possible at the time, the Atari 5200 look of the game can be its strong point, its forte, as the game's ultra simplicity can be refreshing today. Just don't expect to play it as a skill based game, because it doesn't really run so deep, it's more of a brawler in which you can't scroll past the one screen scenario. Eh, well, if you've developed a love story with computer magenta, see International Karate as well or World Karate Championship (Epyx, 1986) as they both offer a similarly themed (both gameplay and looks!) type of game. The mid 80s sure weren't that good to fighting games!
