I'm not sure about you, but "you gotta believe" I'm a sucker for a good rhythm game. Game mechanics are usually boiled down to "hit this button at this time", but in reality all games are the same; rhythm games are just more explicit about it. Since I've moved my gaming stuff into the basement, I've been able to enjoy them a fair bit more than normal, and I figured it would be a good time to go through a few of my favorites (in no particular order).
There's something inherently natural about the desire to make rhythm. Leave a conga drum out in the open, and it's guaranteed to get bopped a bit by random folks passing by. We may not all have perfect timing, but thumping hands in a percussive manner comes as natural as whistling or toe-tapping to pretty much everyone.
In that sense, the real surprise isn't so much the recent rise and fall of music video games, but rather that they haven't had more of a longstanding presence alongside other classic genres. We've pretty much always seen some variant; sound and pattern recognition (endless runners like Temple Run), instrument training (Miracle Piano, Rocksmith), exercise and dancing (Dance Dance Revolution, Pump It Up), abstract music integration and layering (Frequency, Amplitude, Rock Band Blitz) and of course, the playful guitar/band sims (Rock Band, Guitar Hero).
