I loved games, and in my infancy I used to be an "adult playing observer", passing hours watching people inserting 25 peseta coins for additional lifespan in Gauntlet, or trying to consume all Out Run's in-game melodies and the colorful USA-wide scroll. Defender, Space Invaders, Galaxian or Donkey Kong are the first ones I remember, full of charm, in bars, mini-golf resources, or swimming pools near León, with a delicious smell to tapas.
Kung-Fu Master, known in Japan as Spartan X (スパルタンX), is a 1984 beat 'em up arcade game developed and published in Japan by Irem. It was later published in North America by Data East. The Japanese version was based on the Jackie Chan movie Wheels on Meals, known as Spartan X in Japan, and credited "Paragon Films Ltd., Towa Promotion", who produced the film upon which it was based. The game is considered by many to be the first beat 'em up video game, and contains elements of Bruce Lee's Game of Death.
The player takes the role of Keiji Thomas, a man in a Keikogi and slippers. Thomas's girlfriend, Sylvia, has been kidnapped by "Mr. X", and Thomas must fight through five side-scrolling floors full of enemies to rescue her.
Brutally summarized as "rescue girlfriend – hit people", the US and UK version opens with the phrase "Thomas and Sylvia were attacked by several unknown guys....".
