Wii essential!
But as soon as I started playing I instantly became immersed in Santa Destroy, they also start off with an incredibllly useful and in depth (but not boring) tutorial. The controls are amazing and definatley well thought out, it can reconise high and low attacks, and even uses certain motions to achieve wrestling moves, so fun!
Another amazing concept is that the speaker on the wii-mote is the reciever as on a phone, so you have to put it towards your ear to hear instructions etc. just like a normal mobile, I was amazed when this happened, I wasn't really listening to what Sylvie said, oh well.
I also love how the other characters, especially fellow asassins, are designed, they are so exagerated especially when you meet your first opponent, Death Metal.
So even if you phail at games, like me, still buy it, put it on the easiest mode, 'Sweet' and you wont care not being able to do much, you wont get sick of repeating it again later as it is so fresh and individual. AMAZING AMAZING Game, BUY IT!
