Summary: This is the best sonic game yet to come out! This game is the first game I have ever payed on the Sony P.S.P(Play Station Portable), and I won't have to worry about getting another P.S.P game (other than Sonic Rivals 2) for a while. When I first started playing it I was not able to set down. I beat the entire game as Sonic, Knuckles, Shadow, Silver, and Metal Sonic the day after I got the game! I was up until 1:30 A.M playing it.
Summary: This game is so fun and this is the only Sonic game on the PSP (other than Sonic Rivals 2.) Anyway this is really good and probably the best Sega portable game ever! The graphics are satisfactory but it won't bug you when you are playing this game. This game is so good that it should be 30$. So get this because it is worth the 17$. And I'm looking foward to Sonic Rivals 2 when I get it.
