Air guitar is so gloriously impromptu, while guitar hero requires accessories and electricity and things. I don't think it'll ever fade away. Like a steering wheel drum kit, the air guitar is always there when you need it...
I'm more worried about air guitar than the real thing. Air guitar is imaginative and creative; it requires the purely mental conjuration of an alter-ego and scenario, as well as the dexterity of the real guitarist. Now that our kids (and their parents) have this bedazzling gizmo to distract them, will anyone bother to do it the old-fashioned way? Whither morris-dancing, thence goes air guitar.
Yup! We got the wii Rock Band for Christmas. I haven't played a video game since pong and tetris. I've never done karaoke. But try to wrench my Rock Band microphone or guitar out of my hands and you'll pull back a bloody stump!
It's much easier, yarb. But it's not the end; just because you're playing a video game called Rock Band doesn't mean you're actually in a rock band. You start out at "beginner" which is basically teaching you how/when to strum. The next level up (you can pick any level you want, you don't have to go through them from the bottom) adds three "fret" buttons; the next level, four; and the songs get harder as you move through the game.
Guitar Hero is wildly fun--there's also a bass guitar, vocals, and drums, though to play bass guitar at the same time as guitar (with a friend, say), you have to have two of the little guitar doohickeys (they're the same, only you can tell it you want to play the bass line and that's what it will project on the screen). And you have to buy the drum set doohickey separately too.
How does the console come into it? You put the game into the Wii console, put the Wii remote into the guitar-shaped doohickey--the one the guy's playing in the YouTube video pleth linked to--and then you can dance around the room as if you're holding a real (if tiny) guitar. (Guitar Hero versions are available for PlayStation and XBox as well as Wii.)
Thanks ptero! The sad thing is, I actually have played Guitar Hero quite a bit...apparently too much as my ability to string words together into meaningful, um, er, what-cha-ma-call-its... seems to have suffered!
