Sonic Rush Adventure hands-on at Gamespot.

"Just when it seemed like Sonic the Hedgehog was going to wind up as the video game equivalent of performers who hobble over to Vegas to coast on former glories, 2005's Sonic Rush for the DS reminded the masses just why Sega's onetime mascot held his own against Mario back in the day. The title focused on 2D platforming with some 3D peppered in to liven up the action. Given the game's return to Sonic's roots, the DS title was met with open arms by critics and consumers alike, who had suffered through a gamut of titles starring the hedgehog that were less than exciting. Not surprisingly, Sega and Sonic Team have now queued up a sequel to the game, Sonic Rush Adventure. This new game takes the speed and platforming that made the original game pop and adds a new adventure element that includes some Phantom Hourglass-style touch-screen-powered sailing. We had the chance to try out the game to see if Sonic's winning streak on the DS will continue, or if the hedgehog is about to stumble into yet another mediocre adventure."
