this game as a whole feels like a remake of the original sonic the hedgehog 1,2,and 3. since sonic 4 ep 1 is out now, this game is starting to become forgotten. but it's still a great game, and it also adds a unique twist unlike sonic rush. it's a great sequel to sonic rush. when starting the game, we see an opening cinamatic (yes, a fully animated cinamatic) for a handheld system like the DS that is very impressive. and then you explore a hub world and build a water bike, and control it with the touch screen. this really is amazing for a DS title. and then when you get to the first level, you start sonic rush-like gameplay(side scrolling and boosting) then you face a boss, and like the original sonic rush, all boss fights are in bad cgi graphics. if they made the opening cinamatic, the hub world, and the water jet gameplay all in perfect cgi, then why did they ruin all of the boss battles. but if you can get over that problem, then you will enjoy the game, and you will build up to 4 vehicles to get you from island to island and these vehicles are, wave cyclone (water bike), ocean tornado,(ship) aqua blast (hovercraft), and deep typhoon(submerine), all of these vehicles have a diffrent style of gameplay, and they are all perfect. you chase down a pirate named captain whisker through 7 zones, the zones are, plant kingdom, machine labrynith, coral cave, haunted ship, blizzerd peeks, sky babyloon, pirates island, and deep core (deep core zone will only be unlocked if you beat the game and collect all 7 chaos emeralds.) all of these zones are unique in their on speical ways. and this is definetly a game for sonic advance fans, sonic rush fans, or just sonic fans in general, even if you have sonic 4 ep 1 or 2, you should still give this game and sonic rush a try.
yes: I recommend this product
