The flaws are obvious, yet fantards eat this game up like Rouge the Bat to the Master Emerald. The only - ONLY - redeeming quality of the game was the soundtrack, which IMHO is pretty good. Everything else about the game: pure garbage.
Because 06 feels uncannily like the Adventure games. It tries desperately to follow in their mold. Hell, it even rips off SA1's intro stage Orca gimmick.
I liked 06. To be precise, I liked SHADOW's game, because it was what ShTHH SHOULD have been like. Not the emo gun toting mess that it was. (thats not to say i didnt enjoy ShTHH, but lets face it. We all hope it NEVER happens again.)
Silver's game was fun if only because he was just plain DIFFERENT to play as. for once a character who was not a speed power or flying type. He was a psychic type. I must admit, breaking barrels and dicking around with the fruits inside them with telekinesis in the hub world was just plain fun. And fighting enemies was kinda fun too. Different. Although his missions should have handled that psychic gimmick better than they did. More than just "use your power to lift this bridge" or some of the simple stuff you did.
Sonic's game was really the only one that feels bad. Because mainly, the running segments. They are autorunning, with unavoidable obstacles and glitchy physics, (such as that infamous loop de-loop where you always fall off the edge before reaching the boost pad) otherwise, the regular segments, while meeh, were not that bad.
The final boss though, (Solaris) Am i the only one who finds that fight confusing and a b it too tedious at first?
