My son earned some serious brownie points (aka, “blackmail opportunities”) with his sister when he grabbed a spot in the line outside Wal-Mart and held it for her to get a Wii. He and a friend sat there for 8 hours until she joined them after she got out of work. After another 3 or 4 hours, they got the silly thing.
I was a little wary of the whole “wave the controller in the air to play tennis” thing, but holy crap is it fun! I’m glad my kids are old enough to buy their own expensive toys that I can play with.
