Sonic Rush Adventure review at Eurogamer.

"Bad news, Internet. After years of unspoken understanding that if a Sonic game is going to be rubbish they would put "Adventure" in the name, whack a few jet-skis in it or make half of it 3D, Sonic Team has betrayed us all with this week's Sonic Rush sequel - a damn fine DS game that does all of the above. So where did it all go right?

Certainly not in the opening scenes. After Sonic and Tails crash-land on a beach, they find themselves having to collect rocks and minerals from a string of islands in the middle of the ocean, building various watercraft so they can scour further and further afield."
