Revealed through hacking, there also exists additional characters such as characters from the Football Manager series, Shogun: Total War series, as well as an appearance from another non-Sega property, Team Fortress 2. The two Non-Sega characters included are Ralph from the Walt Disney movie Wreck-it Ralph who is in every version, and real professional NASCAR racer Danica Patrick, who is in every version except the mobile versions. They were chosen along with new Sega franchise characters and characters from Non-Sega franchises with additional characters planned for DLC.
The game has characters from several of Sega's previous franchises making their debut in the All-Stars Racing series, including Gilius Thunderhead and Vyse who both were cut from the previous title's roster. The courses also change with different features during each lap, usually changing the routes traveled on during the race, so the courses are always evolving during the race. Each vehicle type handles differently to simulate the differences between the environments (for example roads for cars versus water for boats). The game's surname comes from its new transforming vehicle system, which allows players to traverse land, sea, and sky by transforming their vehicles mid-race via transform gates into cars, boats, and planes, allowing for much more varied tracks.
