Fantastic reunion for Mario and Sonic and a perfect sports game but in track and field is an absolute friendship.
There are 2 teams and they are:
From the Mushroom Kingdom:
Mario
Luigi
Peach
Daisy
Wario
Waluigi
Yoshi
Bowser
From the Emerald Island:
Sonic
Tails
Knuckles
Amy Rose
Blaze
Shadow
Dr Eggman (aka Dr Robotnik which I like to call him)
When you start playingthe game, not all the events are avalible you have to take part in the first 4 circuits to unlock them. To unlock the Moonlight circuit, you need to win gold in the first 4 circuits.
The events are hard to start with but the more practice and learning, you will get used to it and it will be a lot easier.
Archery was one of the hardest events but difficult to master so you need to keep an eye on the wind direction.
100m freestyle is also hard because all the characters have their own method of how to swim but it can be easy when you master it.
The Trampoline was one of my favourite ones because you use the Wii Remote to bounce your character up and down and you have to follow the key commands on the right of the screen and thats excellent.
The Dream events are good but you need to win the circuits to unlock them.
I found table tennis quite good but the timing is a little bit iffy but I like it anyway.
You can also update your records of each event you competed in via Nintendo wifi connection but sadly there's no online play.
The game is based on the 2008 Beijing Olympics and the Graphics are brilliant and the Music Score is absolutely beautifully done.
I bought it cheap for £14.99 after trading Mario Strikers Charged Football at Gamestation and its worth getting.
