Gamasutra speculates that the music and rhythm ‘fad’ in video games may be fading.

Purely anecdotally, it’s hard for me to disagree.  I was a huge Guitar Hero 1 & 2 fan, as evidenced in posts like this one. It’s difficult to overstate how enthusiastic I was about Guitar Hero 1 and 2 and I wouldn’t want to speculate on how many hours I spent playing them.

When Rock Band came out, I eagerly bought it and played it quite a bit, though less than Guitar Hero. I barely played Guitar Hero 3, and have only played Rock Band 2 a few times. I don’t think I’ll even be picking up Guitar Hero World Tour.

The trouble is just that these are all basically the same game, with endless new ‘levels’, and the thrill wears off after awhile, predictably, because the gameplay is fundamentally identical.
