i bought this game after enjoying mario party 6 and was a bit unsure as you had the addition of the mic. To be honest i still havent used the mic as it is only usable on a select few minigames and you can use the controller for these any way. I can imagine it would be more fun for young children. The game itself is good and any one who has played 6 will know what to expect. The board maps are not as good as in mario party 6 but will keep you busy for about 20 hours. The new characters are a welcome addition and sort of makes up for the poor board maps.
If you buy thios game expecting it to be better than 6 dont its about the same some improvements but some dissapointments. If you can pick up for less than £10 worth a go but dont think your getting a good deal paying more as there is a mic with it.
