My boyfriend waited in line (inside Wal-Mart, thank goodness) for about 12 hours. He was the 2nd to last person to get a Wii. He bought an extra controller (w/out the nunchuck, they were out) and Monkey Ball Banana Blitz. He got back at 1:30am last night, and I immediately visited him to go play. It's a blast! You can create avatars called "Mii"s, and when you play Wii Sports you play as the character you created. So far, tennis is my favorite.
I'm not a huge fan of Monkey Ball, but that is also good. I'm just bitter that I didn't go and pick up Rayman Raving Rabbids for myself
