i can't believe how fit the wii can get you after playing for 20 hours in 2 days may arms are dead, and i can hardly move but i can't stop playing it's amazing. my muscles are pumped as and Hard like if i had just been lifting weights for an hour or 2 but this is hilarious fun. i've also lost 2 kgs in 2 days and definately put on muscle. This IS the revolution lol. You can tell in like 5 years when the kids that are getting consoles now going to highschool the kids that had wiis will be really fit and strong, the kids that had 360's will be unfit, and the kids that had ps3s will be really unfit coz the ps3 looks like a grill and makes you hungry LMAO!
