Man this is a great game! And I've managed to get my whole family playing it which is just insane, they're all complete non-gamers but they love it.
Nintendo has real winner here.
The only negative point of this game for me, is Boxing. What a dud!
I dunno, maybe it's just me but it seems to be so unresponsive compared to all the other games, sometimes I have to swing the Wii Remote or Nunchuck about 3 or 4 times to get a single punch!
Everything else about Wii Sports is fantastic though, I love the Wii Fitness thing too, my Wii Fitness age went down from 38 to 27 today!
