Of course. Not everyone is nostalgic. I am certainly not nostalgic. I struggled playing through the old Final Fantasies, but I knew I can't consider myself an actual fan unless I played them all at least.
You see, the reason I am disappointed is because when they named it "Sonic the Hedgehog", I am thinking that they are taking it back to his debut, and making an entirely new game. I am sure I am not the only one that thought that. Yet, it was nothing but Sonic Adventure 3.
Sega really pisses me off when they do that. They are the opposite of Square-Enix, in my opinion. Square will do something a lot greater than what most of us expect. They give it a title trying to make us expect something different and solely to Sonic.
I don't hate Knuckles and Tails. I like those characters, which is why I thought Sonic Heroes was ok. But it seems like when they give Sonic his own role, they give him a random one that doesn't make any sense to his character.
