My kids have a WII. At first it wasn't too good because of the shortage of games, but now there are plenty for them.
They have a playstation, Xbox and WII, and personal, I like them to play on the wii because they aren't just sat around all day..... with the Wii it keeps them active, and when they go to bed, its a great console to get all adults together for a game of COMPETITIVE bowling lol
