My Wii arrived on the day of launch but Zelda and Super Monkey Ball didnt so popped out to get Gundam Scad Hammer which I was thinking of getting anyway - tis a brilliant game and probably the best out of the Wii, PS3 and XBOX360 bunch of Gundam launch titles. You can check out the promo trailer at YouTube and more movies of the game at the official site.
You start off with Gundam and he (do we call Gundam a 'he' ? Please advise) has a ball n chain which you swing at Zak's and Acguy's etc. If you swing the controller as if you are really swinging a ball n chain (which we all obviously do in real life from time to time), Gundam will do the same. If you thrust the controller out in front, the ball and chain lashes out to hit the MS infront. The instructions actually state that you don’t need to swing the remote around the room like a ball and chain!
There are usual big bosses to overcome at the end of stages - some of which involve you jumping in the air and swinging the ball n chain. Consider getting it but be warned that you will have aching arms after a few hours. Folks in Japan can get it at #''#B000FNSZ90,スカッドハンマーズ,Amazon#''#.
