As an 'open zone' game, I don't neccessarily think this game is bad, but I really honestly think Sonic games need to take a page out of Sonic Robo Blast 2 level design. A fine boost sonic game, but missing some of the things that could really make boost sonic shine in a real 3D platformer. The scenery is beautiful, but the flying rails, platforms, etc, they take away from the raw beauty of the rest of the game world. Combat is fine.
