I don't know your boyfriend. So it's hard to say. I'd think that Rhythm Party would be more universally appealing. If he ever played Elite Beat Agents on the DS and liked it, he will probably like Rhythm Party. He might like it even if he never has. It is basically the gameplay of that, but hitting the circles with your hands and feet. There's ones you just hit, ones you have to swipe at in a certain direction and ones you have to hold. Then you can add in improv tricks like spinning, jumping, hitting hand markers with your feet, etc. That increases your multiplier. It has fun visual effects too. Fruit Ninja Kinect is hard not to like too.
