While it has its selection of flaws this is a good Sonic game.
Story
Welll the story begins Sonic is sleeping and comes across a book and a gneie names Sharara tells him that an evil genie called the Erazor Djinn is destroying the pages out of the Arbian Nights. Sonic is then transported in the book and is hit with a flame by the Erazor Djinn saying if the flame goes out it is over for Sonic. He is also told that he is a sacrifice as well.
Gameplay
The game is played using just the Wii mote and you move the remote left and right in which direction you want to go. You defeat enemies with a homing attack and to jump you hold down the 2 button to perform a jump the longer you hold it down the higher you jump and if you see a red cursor you thrust the Wii mote forward to do an attack which I felt was a nice idea. The game has a few nice missions and a tutorial to learn the basic techniques. The game can be challeneging espcally the bosses. So whats the downside to the gameplay well the fact you are always going forward and that most levels can be hard to get through straight away but I do like the idea you don't have to worry about running out of lives. I also like the idea of being able to have abilites and you can customise your abilities and have them for different levels. I like the idea of speed break if you press up you go into a very fast speed and time break which is slow so you can get past obstacles better but you need enoughorb power to be able to perform them. The cutscnes are not that good though.
Sound and graphics
The sound is okay but can get annoying epscially that annoying genie but one thing I do like is the graphics it is a very nice looking game for a Wii game.
Lastablity
There is about a good 20 to 40 hours you will spend playing this game and if you have friends you might want to play some mini games in the party section but that is a bit pointless but some might like it. There are tons of missions to do even if you complete the game but achieveing gold medals is hard.
Overall Opinion
This is not a bad game at all. It is very fun because you are only playing as Sonic the Hedgehog and it is what a Sonic game is about. While the story is a bit off and that some levels can be annoying first few tries it is a very solid title worth playing. Overall it is certainly better than most 3D Sonic games that have come out.
