Sonic & All-Stars Racing Transformed

Sonic & All-Stars Racing Transformed is the sequel for the first racing game of the SEGA Superstars series. The game was leaked by Kotaku at the New York Toy Fair by revealing, according to Kotaku, "Sega's Sequel to Sonic and Sega All-Stars Racing". Pictures depicting the side-view of the shelf revealed boxes for Sonic the Hedgehog, Miles "Tails" Prower, Beat, and Aiai. Shortly after this event the website called Starland.com also added info on the game. They listed it in the pre-order list for the PS3, Xbox 360 and Wii. It was listed as $57 for pre-order. This was then removed by SEGA at the website. It was also listed for release on 11/30/12.

On April 30th, an announcement trailer was released revealing the game's official name as well as a new mechanic that transforms the character's vehicles to land, air and water capable forms. The confirmed platforms of release are PS3, Xbox 360, Wii U, PC, Vita and 3DS.

You will be able to earn points to put towards a leveling system, which can potentially unlock vehicle mods and other items, and goodies.

Gameplay
Gameplay, for the most part, is the same as in the prequel, where you choose different settings and characters before a race. The biggest edition to the game is the 3 different modes of racing: on land, sea and air, a concept previously used in Diddy Kong Racing and Mario Kart 7. The karts can now change into a plane when in the air and a boat when on water. The Sumo Digital staff have said in some interviews that it will be 'proper boating, proper flying and improved kart racing', almost has if it's 3 racing games in one.

All-Star Moves and other items, such as mines, are returning, though there will be special stars that'll power up a meter for the All-Star Moves, and once full, the player can use it anytime, any racing position. It has been shown in footage by IGN that there are different or new weapons; two of the known weapons is a snowman's head that sends shots of ice that'll freeze the racers and a baseball glove that catches the item from behind. There are also 16 new tracks, plus 4 favorite tracks from the old game, one includes the Shibuya Downtown track.

Playable Characters
So far, 29 playable characters (including three 3rd party characters) have been confirmed to appear in this game. It has also been said that the game will feature platform specific rosters, and no single platform has all 29. 17 of the full confirmed number of racers include:

Trivia

 * This is the second time in which a Sonic game was leaked due to the premature release of toys, the first time being when toys of Rouge the Bat and Shadow the Hedgehog had been revealed before both characters' debuting game, Sonic Adventure 2, was even announced, both of which happen to be sequels.
 * This game is very similar to Hot Wheels Extreme Racing for the Playstation 1, a game which also utilised the abilty to transform into a plane and boat during gameplay.
 * Sumo Digital claims that they had the idea of the transforming vehicles before Mario Kart 7 was announced.
 * Unlike the first game, the PC version will feature online multiplayer.
 * There is a minor change in the title from the first All-Stars Racing game as the "SEGA" is missing, just making it Sonic & All-Stars Racing Transformed rather than Sonic & SEGA All-Stars Racing Transformed. This was most likely just an effort to make the title shorter.
 * All-Stars Racing Transformed uses the song "Promises" by Nero for the BGM of the trailers.
 * This makes All-Stars Racing Transformed the second Sonic game to have a trailer that uses non-Sega music, the first being Sonic Generations which had trailers that used the songs "Tenderoni" by Kele for the Gameplay/Green Hill trailer and "Na Na Na" by My Chemical Romance for the City Escape trailer.
 * Although Beat appeared in the first All-Stars Racing game with his Jet Set Radio Future design, he appears in All-Stars Racing Transformed with his original design from Jet Set Radio.
 * The Karts in the game have undergone a radical design change, probably due to the transformation mechanics in this game. Notable examples include Sonic's Speed Star which now has sharper angles, different wheels, and less "Sonic spines", Amy's car loses the tire cover and gets a bigger wind shield and becomes rounded, and Doctor Eggman's monster truck now is a unknown six-wheeled red "tank". Every racer now has a kart, a tank-like vehicle or a quad bike instead of a bi-plane (e.g. Tails' Tornado Racer) and a motorcycle (e.g. Shadow's Dark Rider).
 * This is the first Sonic the Hedgehog game (as well as the first spin-off title) on the PlayStation Vita (not counting PSP re-releases on the PlayStation Network) and the Wii U.
 * By the end of the Comic-Con 2012 trailer, some of Sonic's voice clips from Sonic Generations are used.
 * Wreck-It-Ralph, from the 2012 Disney film of the same name, is a playable character in the game, which is most likely a reference to the fact that in the film, Ralph 'game jumps' through different arcade games until he eventually comes across the Hero's Duty shooter game and a kart racing arcade game called Sugar Rush.
