Sonic & SEGA All-Star Racing
Mario Kart clone? Yes
In a frantic battle to the chequered flag, Sonic and friends speed around tracks set in mediaeval castle ramparts, lush rainforests and bustling cities, all taken from the visually rich and varied universes of Sonic and SEGA. Fan favourites such as Dr. Eggman, Tails, AiAi, Amigo and many more will join Sonic in their custom built vehicles, revving their engines and jostling to stay ahead of the pack. Each character will speed around the track in cars, planes, motorbikes, and in Aiai’s case – a banana mobile! Secret short cuts, swift handling and avoiding strategically placed obstacles are certainly the best way to get to the top of the podium…
But winning is only part of the fun in Sonic & SEGA All-Stars Racing! Each character has a specific All Star move – such as Super Sonic, Banana Blitz and Tails Tornado – that allows a quick way for competitors to get back into the race! Power ups and weapons can also be collected around the tracks and used against the opposition to ensure they don’t become a threat to that number one position.
Battle it out in single or multiplayer mode, allowing up to four friends to race in frantic split-screen action, or up to eight players to compete online in the ultimate racing showdown.
Will we still try it? Probably
I don't think SEGAs characters are as interesting as Nintendos but this could open up future possibilties of a SEGA/Mario Kart crossover in the future.
