Never touched black knight or secret rings or 06. Its not even just about it being too easy. There is a SEVERE lack of gameplay. Sure you can argue that someone is holding forward/up and pressing jump now and then and some quicktime events, but that doesn't measure anywhere NEAR a real game imo. I just don't like how there is a strict 1 way to get where you are going AND there is almost no way to screw it up. The only 3D sonic game i could stand to play all the way through was Sonic Heroes and it had enemies that required SOMETHING to fight. Spiked enemies with guns, enemies with shileds that had to be circles, armored enemies that required the use of Sonic tornado or switching to Knuckles.
