Anyone with a ps2, xbox, or wii should definitely buy Dance Dance Revolution. It's an awesome game for weight loss, plus it's addictive. I get bored just walking/jogging, so I bought this game and have been playing it for about 1/2 hour every day for about 6 months. Difficulty ranges from very, very simple to almost impossible, so there's something for everyone. It's a great workout, and some of the versions have a "workout mode" that counts how many calories you burn.
