In response to the success of their racing titles, particularly the Shutokou Battle series, Genki established a division dedicated to that genre in 2003 called the Genki Racing Project, or GRP. The GRP's first title was Shutokou Battle Online for Microsoft Windows, which tried to apply an MMO-like aspect to the existing gameplay of the series. The game and its update version were sold only in Japan but were playable from anywhere as free online trial versions (with free registration) were available for download on the game's website.
