To me the BEST good game since 4Kids voice acting got into this. Infact, best in a while, FINALLY!
GAMEPLAY:
For a side scoller Sonic game, perfect, it offered a lot of elements from the old game and the new ones to keep it good on side scrolling style, plus with MANY new stuff to increase the speed for what Sonic stands for to an unbelieveable level. You can not go wrong here.
GRAPHICS:
I don't really care for graphics and I find they are an over rated thing that gets stupid people into buying something that sucks. But to be honest, best graphics I have seen in a portable Sonic game. And I need to be fair as well
SOUND:
MUSIC:
The music is very very cool, now it's something I would like to rip from the game and listen to while I work or something.
EFFECTS:
The effects are pretty good. Dashing, some classic ones from past Sonic games, and a few others
VOICES:
The voices are terrible and out of character, The only decent ones are Eggman and Blaze. Tails sounds nothing like a child anymore which is something I have known him as since Adventures of Sonic the Hedgehog but I will admit his voice from Amy Palant in this game is tolerable. Sonic on the other hand sounds lame and emotionless, like he is faking how he feels, which I find horrible as Sonic is the main character, in the previous Handheld games with voices, Sonic was awesome, I didn't think a different actor could kill it in a game with clips, but boy was I proven wrong. Cream sounds screechy and it gives me a headache, she sounds nothing like a child anymore, in fact it's SO bad I nearly want to kill myself. While the voices are why this is my low sound score rating, as Jason Griffith's take on Sonic in this game is just so horrible, it ruins Sonic's Character completely, not to mention his voice alone is just overall inappropriate for Sonic even with better acting. I sold the game after the first week to replace it with the Japanese version. The Japanese version is in NO WAY bad, Japanese voices that are in character and non ear bleeding, and just all around fun.
OVERALL:
Off all side scollers I would recommend this one the most, but if you can, import the Japanese version, for me as a fan of the characters and just over all, the voices and their acting in the US version just kills the experience in the game if you are a fan of the characters. If it wasn't for that, I would give this game a 10, but I give the Japanese version a ten none the less as it's easier on vocal sound. Still in a game of anything side scrolling, I don't think you will get anything better in speed.
