I've played with it. My neice has it. The "boxing" game is fun.
However, the novelty wears off pretty quickly. It's alright for a few minutes of play at a party or something, but it doesn't have the kind of game play that will suck someone in for several hours.
The technology needs to be improved a bit too. A lot of times, movement and touching things flying around the screen does not register, and is quite annoying.
Kids will like it. Maybe grandparents too.
Hardcore gamers? No.
Verdict: It's okay, but not highly recommended.
