Good game, but you should rent it first, just to make sure.
One of the best looking Sonic games ever. Daytime stages are fast and fun to play. A good variety of level settings. Frame Rate is impressive even when the game is at top speed.
The Bad:
Frame Rate is impressive but it drops a lot during werehog stages. Story is hard to get into. Werehog is extremely unnecessary and overrules the number of daytime stages. Tons of great Sonic characters were taken out. Sometimes the game is too hard.
Gameplay: 6. There is only a story mode to it. No multiplayer, not even locally.
Graphics Artistic: 10. Has a great use of the hedgehog engine. Produces beautiful colors of all shapes.
Graphics technical: 6. The daytime stages' Frame rate always stays consistent, but the nighttime stages suffer from Frame rate issues.
Value: 7. Some of the levels are worth coming back to but not all.
Sound: 8. The sound effects are overall good but could have been better. Music is also really good, too. It fits the stages very well and it's most of the time peaceful. The only music that's annoying is when you fight enemies during the werehog stages.
To me, I think this is the comeback for Sonic after some of his last disasters. It improves upon many of the previous games' problems, like the camera, glitches, and the overall quality of the game. There are seven worlds, even though I haven't gotten to all of them. Each world has its little relationship between a real-life country. While playing through the game, you'll collect these sun medals, and moon medals, sort of similar to the emblems system in the sonic adventures. By collecting these medals, you can unlock new levels to play in. The game starts off like a normal Sonic game. Eggman tries to take over the world for the hundredth time. Sonic gets turned into a werehog only at nighttime. Because of this, the Earth separates into different pieces, and sonic must use the power of the chaos emeralds to restore the planet. On the way, you meet this annoying little fairy that has forgotten his own name. The fairy sticks with Sonic and then Sonic comes up with a name called Chip. Totally fits him, doesn't it? I hope you found this review helpful to you.
