It is the second installment in the Street Fighter series and the sequel to 1987's Street Fighter. It is Capcom's fourteenth game 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, a combo system, a six-button configuration, and a wider selection of playable characters, each with a unique fighting style.

Street Fighter II became the best-selling game since the golden age of arcade video games. By 1994, it had been played by at least 25 million people in the United States alone.

Street Fighter II is regarded as one of the greatest video games of all time and the most important and influential fighting game ever made. Its launch is seen as a revolutionary moment within its genre, credited with popularizing the fighting genre during the 1990s and inspiring other producers to create their own fighting series.
