When Guitar Hero or Rock Band come up in conversation, I always feel a little like Stan's dad in this recent episode of South Park (fast forward to 0:45 if you're in a hurry).
I feel a little better since yesterday, when Sleater-Kinney guitarist Carrie Brownstein published her review of Rock Band in Slate, in which she compares playing Rock Band with playing in a rock band. It's a fun read, so I won't summarize it here, but the following quote pretty much nails it for me: "And, really, if you are going to play the game with a group of friends for more than a night, shouldn't you just form a real band? There is something sad about the thought of four teenagers getting Rock Band for Christmas and spending all of their after-school time pretending to know how to play."
And before you accuse me of sounding like an 80-year-old, yes, I've tried Guitar Hero and can see how it might be addictive. The drums in Rock Band also seem appealing, although I haven't seen that game in action yet.
