The Guitar Hero journey hasn't been all sunshine and rainbows. The brand has grown so quickly that we might have forgotten what it took to get here.
Guitar Hero (2005)

I remember vividly the night I first played Guitar Hero. I wasn't reviewing it. In fact, a staff writer at the paper had written a feature on Harmonix, and didn't want the promo copy they gave her. So she gave it to my roommate at the time, another Phoenix staffer, and he brought it home. We each felt a little silly when we first slung that guitar over our shoulders, but that lasted for about one note. We spent the rest of the night trading off songs, working our way through most of the setlist. It was just as I remember playing games as a kid. We weren't scrutinizing anything. We were just enjoying ourselves, jumping up from the couch as soon as the other person had finished a track.
It was awesome.
Guitar Hero II (2006)

Otherwise, the game was a spit and polish. An expanded tracklist and snazzier graphics were welcome, even if nothing else seemed as revolutionary as the co-op. An Xbox 360 port in the spring of 2007 added HD graphics, downloadable content, and a new guitar peripheral.
It was so awesome.
Guitar Hero Encore: Rocks the 80s (2007)

It pretty much sucked.
Guitar Hero III: Legends of Rock (2007)

Legends also made a few critical missteps, which called into question Neversoft's judgment. What had always distinguished the Guitar Hero series in the world of video games was how unlike most other games it seemed. It could be brutally difficult, yes, and demanded much of your hand-eye coordination. But it was accessible in a way that most game genres aren't, and its system of rewards and punishment appealing to non-gamers.
That's why it was so troubling that Neversoft added boss battles, wherein you played dueling guitar parts against Tom Morello, Slash, and even Satan, deploying Mario Kart-style powerups along the way. You can forgive them for trying something new, even if it didn't work, but the battles seemed to violate the spirit that had made Guitar Hero such a phenemoneon. They traded the joy of performance for the capricious challenge of ordinary video games.
It was good, but troubling.
Guitar Hero: On Tour (2008)

On the other hand -- the hand that you used to press the fret buttons -- the peripheral was painful to use. I mean that literally. 20 minutes of Guitar Hero: On Tour was enough to send shockwaves from my wrist up to my elbow. I recently opted not to click on a link where somebody from the dev team explained how they went through several iterations before settling on the final design of the peripheral. They should have iterated more.
Even more painful: the tracklist included songs by Maroon 5 and Smash Mouth.
Holy shit was it bad.
Guitar Hero: Aerosmith (2008)

The real problem with Guitar Hero: Aerosmith, though, was that it came out a good 6 months after Rock Band, and a guitar-only music game no longer seemed sufficient. Where were the drums? The vocals? The robust multiplayer that, thanks to Harmonix's new game, had come to define music and rhythm games? Aerosmith seemed like a cash-in at best.
It was terrible.
Guitar Hero: World Tour (2008)

It was all right, but the drum kit didn't work very well.
Guitar Hero: Metallica (2009)

The songs cover the breadth of Metallica's career, from their early thrash metal to the soulful power ballads of the black album. (And, yes, the band's entire 1996-2009 output is also well represented. I avoided it then, and I'm avoiding now.) The non-Metallica tracks are up to that standard, as well. Alice in Chains, Mastodon, Queen, Slayer, Thin Lizzy -- there's a range of styles and eras on offer, and all sterling examples of their type.
I still prefer Rock Band, for a couple of reasons. For one thing, when MTV released an AC/DC track pack, they also allowed you export the songs to your hard drive and play them in Rock Band proper. Harmonix's game still feels better to me, devoid of extraneous graphical flourishes and attempts to sex up the act of matching notes onscreen. But Metallica is probably the best Guitar Hero product to come down the pike at least since Legends of Rock, if not Guitar Hero II.
It's good! But maybe they ought to quit while they're ahead.
