Bioware takes the Sonic universe, and makes it into one of the most unique RPG's of all time.
Story: The game is set a year after Sonic and his friends have defeated Dr. Eggman, while traveling around the world, Sonic gets a call from Tails and learns that Knuckles and been kidnapped by a mysterious new enemy called the Marauders, and the worlds chaos emeralds are disappearing. While this is a good story the pacing is a little bit of, it does have it's fair share of turning points, but it seems like the sort of thing that would happen in a cartoon. The highlights of the story are the comic book inspired cutscenes which last only briefly, but they rock none the less.
Gameplay: You play as either Sonic or one of his friends as you explore vast and different environments the game has to offer. While your exploring you may come across an icon, you switch to the right character to preform an action with the tap of the L or R buttons, this will include having sonic run around loops or Tails flying from one point to another. Instead of random battles you have to bump into enemies to trigger battles, during the battles you pull of POW moves which are the games special moves, to do this have to preform a certain kind of action with the stylus pen such as taping the screen at the right moment or dragging the stylus across the screen. This works surprisingly well since many of these are easy to pull of. Aside from individual POW moves there is also team moves which require more than one character and both have to use up POW energy, but there are more powerful and great to use. The only complaint i have with this is that some are unforgiving, mainly the support moves like when your trying to heal one character with another, if you screw up once then you don't get to continue and you've wasted your POW points. These battle can also drag on for a little bit to long mainly because you will fight tougher enemies in the game with more health and more defense, some enemies are just to strong and take to long to take down, but that still doesn't ruin the battle system.
Design: You move your character using the stylus pen much like in Zelda: Phantom hourglass, again this works since you can steer Sonic in any direction pretty easily. You will never get lost thanks to the map on the top screen which tells you where you are. Also on top of the main quest there are also some side quests that you can accept which help extend the length of the game, like there's one that has you going of killing a giant queen wasp. The biggest complaint i have with this game are the lackluster boss battles, the game has a theme song for bosses, but none of them are memorable mainly because they feel to much like regular enemies, except for maybe the final boss. There are also puzzles you have to solve which you need to trigger by talking to someone, these can be easy sometimes but it's a little a tricky unless you ask the person for a tip which costs 30 rings, kind of expensive considering you just want to know how the puzzle works, but again this doesn't ruin the game.
Overall: Sonic chronicles the dark brotherhood has a unique battle system, colorful design and is just down right fun to play. It's one of the best Sonic games of all time.
