"River City Ransom, released as Downtown Nekketsu Monogatari (ダウンタウン熱血物語, Dauntaun Nekketsu Monogatari, "Downtown Hot-Blooded Story") in Japan and as Street Gangs in the PAL region, is a video game for the Family Computer/Nintendo Entertainment System, originally released in 1989. It was one of the first console games published by North American subsidiary American Technos.
It is the third game in Technos' Kunio-kun series released for the Famicom, preceded by Nekketsu Kōha Kunio-kun (Renegade) and Nekketsu Kōkō Dodgeball Bu (Super Dodge Ball). Like its predecessors, Monogatari underwent great changes in its storyline and graphical presentation during its localization in order to make the game more palatable in the western market."
