Got my wii yesterday. Set it up and never stopped playing Wii sports.
Hands down its the most fun i've had in 15+ years between mmpogs, first person shooters, other consoles, civ games, you name it. I really felt like a kid again.
I only have 2 controllers but we had 3 people total and the other person that I invited over within 30 minutes of playing it said he is going to buy a wii. Not to take any fanboy shots against PS3 or Xbox lovers but the wii is 'the fun one!'
