Looks and sounds great.Gamerz-Edge said:This game really hooked me fast. After just the first zone, I was having so much fun that I bumped it up a few spots on my holiday gift guide. Who knew wed be getting a Sonic game this good for the Nintendo DS? From the classic level designs to the stunning boss battles, this game is just classic Sonic the Hedgehog all over again; its without a doubt the best one in years probably since Sonic & Knuckles. When a game is such a joy to play, you know youve got something special on your hands. Sonic Rush is the most traditional yet appropriately progressive installment that the series has seen in a long time.
