Street Fighter Ken (Arcade 1987

Street Fighter is the first fighting game in the legendary series. The player controls martial artist Ryu, who travels the world to battle various international fighters. The main goal is to become the world's strongest warrior.
The game introduced the core concepts of the series, including special moves like the Hadouken and Shoryuken, which required specific joystick and button motions to perform. A second player could join in to play as Ken, Ryu's rival and fellow fighter. It laid the foundation for the one-on-one fighting game genre, but was much simpler and less polished than its famous sequel, Street Fighter II.
