Tied for the greatest sonic game along with sonic and knuckles in my opinion
User Rating: 10 | Sonic Rivals PSP
This game is great! It has everything you want in a sonic game! It even included silver in it! A new villan, an interesting story and more make this game a sonic fan must buy. It feels great to play it on the PSP and has a deep challenge mode that anyone will like. It has more action than the average sonic game with tons of combat when you catch up to your opponent and has a cool list of stuff to do. And for people who say that it has "frusturating" jumps, the jumps are a challenge a way to enjoy on foot racing and shoots way up from the failed attempts before that(sonic the hedgehog,shadow the game). I'd try to say bad thing about the game but there sismply arent any. It's just to amazing.
