To come with direct competition with the Mario Kart series, SEGA came with hopes of making a move into the racing market with the releases of Sonic & SEGA All-Stars Racing in 2010 for the Wii and the DS. With the second installment, Sonic & All-Stars Racing Transformed, releasing in 2012, which saw the release of Wii U as part of its launch lineup then later also releasing on the 3DS.

Both games had positive reception from the audience, with the first installment scoring a 78 on Metacritic and the second scoring a 79 on Metacritic respectively. Now that time has passed, website Sonic Stadium has uncovered some unreleased concept art ranging from both games of the series. Interestingly enough, Gilius Thunderhead from Golden Axe were cut and never saw the light in neither previously released installments.

Not only was it characters whom were butchered from the games, it also included some stages some vehicles which went through long process before reaching the final form, such as AiAi who went through lots of redesigns.
