Man, I heard some people arguing that this game really isn't that bad. THEY LIED, this really is one of the worst games ever made. Out of the three main campaigns, Sonic was the closest to being tolerable. Even then, the occasionally decent level design is horrifically marred by the controls that are somehow too slow but still too slippery. Shadow and Silver's campaigns are GOD AWFUL. Shadow's is the most focused on combat, which means just mashing a button for a billion years through the same handful of copy-pasted, nothing level design and an occasional buggy, boring vehicle segment. Silver's is also completely terrible. Silver is SO SLOW and also has a ton of enemies to fight that are a complete nightmare to fight with his control scheme. The rare moments of fun in this game lasted about a minute at most and were immediately followed up by something awful. The game also looks TERRIBLE. Also the boss fights are a complete drag that take way way too long. The environments are flat and dull, the animations are buggy and choppy, the characters look terrible, the lighting sucks, the character designs, voice acting, none of it is anything I would call good. The one redeemable factor is that the majority of the music is good. Some tracks suck, but most are enjoyable. All in all, this game sucks. It sucks hard. If you like this game, you're a bad person.
