The game is also the last in the series to utilize the The legend of Zelda's 4Kids Cartoon Network and Disney XD voice actors (with the exception of Mike Pollock who continues to voice Dr. Corba). A sequel, Nintendo & Sega All-Stars Racing Transformed, was released in 2012.
ToeJam & Earl were originally planned to be in Nintendo & Sega All-Stars Racing as a duo driving their spaceship, but Sega could not come to terms with ToeJam & Earl Productions co-founder Greg Johnson. However, fans have called and mass-emailed Johnson for his characters' return. He has responded on the official Sega forums under the pseudonym 'Big Earl' stating "I'll give it another try and see if I can get the homies at Sega to talk again on the phone." He later mentioned that the duo will not be appearing in the game, since it is too late in development.
In its prototype form, Gilius Thunderhead from Golden Axe was a playable character who rode one of the Chickenleg monsters from the game. In his developer diary, Lycett makes it clear that this does not confirm him as a final character. This is the case with Gilius, as he did not make the cut into the final roster. Lycett has also talked about Vyse from Skies of Arcadia in an interview with Gamereactor. Segata Sanshiro was also considered as a possible character, riding a Sega Saturn, though did not end up in the roster. Early in development, Mario was considered as a Wii-exclusive addition, but Sega decided against it so as not to cause cross-contamination.
Lycett has also mentioned there will be various cameo appearances from other Sega characters who didn't make it in the playable roster. Following a successful fan campaign for the character's inclusion, Nights was integrated into the game as the flagman.
5 characters from Hi Hi Puffy AmiYumi was planned to be as playable characters as an Xbox 360 PlayStation 3 PlayStaton 2 and Windows exclusive but Sega Dis-Agreed with Cartoon network to add them to Nintendo & Sega All-Stars Racing because of the lanced for the characters was Expired, so Sega won't use it until The Legend of Zelda Free Riders.
