At a Nintendo preview event in New York City about four weeks ago, after I had the opportunity to play the very silly music game Rhythm Heaven Groove, a rep for Nintendo asked me what I thought of it. I told her that what I was about to say was meant in the nicest possible way: the game, I said, was so dumb. Recognizing this compliment sounded like an insult, I emphasized that I adore Rhythm Heaven games. I’ve relished them since I imported the Japanese original for my Game Boy Advance in 2006.
