The game's producer, Joe Neate, said in an interview :

"A thrilling new racing experience featuring Sonic the Hedgehog and a fantastic cast of Sega All-Stars competing across land, air and water in vehicles that fully transform from cars, to planes to boats".

"The key thing is that vehicles can transform, so you can not only race on land but on water and in the air too. There can be up to three surfaces per track, meaning you can have cars racing alongside boats during certain sections, for example."

"The second part of the transformation element is that the tracks can transform in different ways."

Buying this just for Gilius Thunderhead. And no, it won't compete with Mario Kart. It will completely destroy it.

This was announced a while ago. It sounds pretty great.

plz save sega guys

Aww... what a sad sad plea! XD

Said it once, I'll say it again, no Toe Jam & Earl, no buy.

LOL..."no Toe Jam & Earl'....

The game looks pretty good, and it has some new in game innovations.

Can it compete with Mario Kart, its a possibility, since its going to be available

for all consoles, handhelds and PC.  Mario Kart is only available for the Nintendo Consoles,

and this could be the reason it can take off and compete with Mario Kart, since its on

all consoles, handhelds and PC.

Almost ancient news :P
