When you think of Sonic, the first thing that comes to your mind is speed. And this game had none of it.
1. Sonic has no speed
2. The music is mediocre
and 3. The storyline is incredibly stupid
I'm not 100% sure, but I don't think any of those things makes a good sonic game.
The reason Sonic is so slow in this game is because Dr. Robotnik has taken away your speed shoes or something.... I always thought that Sonic was always naturally fast.
And at the end of each zone/level, it tells you how fast you were going. And there's no way that is was right. I think Mario could walk faster thtan how fast sonic was going. This game is God awful.
