Incredibly underrated...
This game is pretty decent compared to the other 3D Sonic games. Seriously you guys that think is bad are either judging it on the Werehog or are just being cry-babies and are still holding grudges against Sonic (seriously, let it go).
This game has some goods points while having certain bad ones.
I'll start with the bad: (1) The Werehog levels lack proper design and also the battle music sucks. (2) The stupid token system cos it seriously slows down the game by miles. (3) No Knuckles, no Shadow and no Silver. Sega have gotten mixed up with the hating of too many characters so they've went and only put in a few. And (4) Chip's voice. I like Chip himself but I hate his English voice that makes him sound all...well, like a dork.
The good points: (1) Sonic is finally incredibly fast without the aid of boosters. (2) The Towns and Villages don't get in the way they did in Next-gen. (3) Jason Grififth has improved as Sonic and Mike Pollack is better than before (aka: He's epic). (4) The fighting in the Werehog levels. When you minus the frequent puzzles and crappy music you might like it. (5) The humour in it. The main character for humour is Chip. He's actually funny at times and has a strange obsession towards food. And finally the graphics are amazing. The music is alright but not as good as the music of the Sonic Adventure series.
This game has really improved. It isn't the same as Sonic Adventure 1 and 2 but it is the best sonic game that was made after Sonic Adventure 2. Sonic isn't back at his greatness, yet, but Sega are getting it right for once. If they continue it like this and take some of the stuff, that sucks, away then perhaps Sonic will be close enough to his old peak. He'll never be the same but he can improve.
