This seems to be the cheapest price I can find this anywhere. There seem to be quite a number of cd-wow vouchers on the voucher page so it might be worth taking your pick from them before you make a purchase.
Wario and his pals learn fun, wacky moves after discovering a strange book and a mystical device called the Form Baton.
The WarioWare team took an idea so wacky, it could only be made with the latest technology... the Wii Remote. Players must clear fast-paced sets of microgames, changing the way they hold the Wii Remote each time. As they do, they'll unlock more microgames and souvenirs. The game's full-body controls add a whole new level of insanity to an already frenetic experience.
