Street Fighter II: The World Warrior is a competitive fighting game developed by Capcom and originally released for arcade systems in 1991. It is the second installment in the Street Fighter series and the sequel to Street Fighter, released in 1987. It prominently features a popular two-player mode that obligates direct, human-to-human competitive play which prolonged the survival of the declining video game arcade business market itself by not only stimulating business but driving the genre of similar games. Additionally, it inspired groups of competitive players to organize self-run tournament events, eventually culminating into EVO. Street Fighter II also shifted the competitive dynamic in video game arcades from one of ability to obtain the highest score, to one of ability requiring winning games directly against other human players, and other human players of large groups only possible in its two-player mode. It is Capcom's fourteenth title to use the CP System arcade system board. Street Fighter II improved many of the concepts introduced in the first game, including the use of special command-based moves and a six-button configuration, while offering players a wider selection of playable characters, each with their own fighting style and introducing the combo system.
