Confession: With exception to a couple of songs, I haven’t played Rock Band or Guitar Hero this year, whereas I played it religiously from 2006-2008 before getting a little burned out. All of that will change on Sept. 9, though, with the release of Beatles Rock Band, which marries two things I like a lot: rhythm games and Beatles music. So are the Fab Four enough to rekindle your interest in music games? Or is the fad over?
