Guitar Hero III: Legends of Rock has five buttons and a strum bar. Rock Band has five buttons and a strum bar. The interface is the same. Despite these similarities, however, there's no assurance your guitar will actually work in both games. Rock Band's virtual axe doesn't function in Guitar Hero III, but Guitar Hero III's guitar does work in Rock Band -- on Xbox 360, anyway. On the PlayStation 3, Guitar Hero III's guitar doesn't work in Rock Band.
Confused? You should be. 1UP are tired of being confused, too. To try and clear the air, 1UP rang Red Octane's co-founder and VP of Business Development, Charles Huang, to speak at length about the confusing consumer issue -- and why it hasn't been resolved yet.
Now both games are on the market and, currently, there's no way for anyone to use their Rock Band controller in the Guitar Hero series. Apparently, however, Rock Band's guitar issues are a roadblock. "I don't think we're too interested in having their guitars work on our game, because they're having a lot of issues with their guitars," said Huang. "From our standpoint, to be quite honest, if you know a competitor's product has issues, there's not a whole lot of motivation to make these problematic controllers work with your game. Why would you want to cause yourself the headache?"

TheGamer Writes "Harmonix has proven plenty of times it can make Rock Band work without instruments."
I mean, yeah, but was anyone saying otherwise? The fact is people liked the plastic instruments rather than pressing buttons on a controller. They enjoyed the simulated experience.
"Work"? No, but to be good? It's absolutely necessary. Not having the accessories is like playing a lightgun shooter with an analog stick sure it works, but one experience is completely unique and fun as hell, and other is torture trying to make do playing in a way it was never meant to be played
I think CHEAP plastic instruments is THE reason why the instrument-genre ‘died’.
People invested in buying the game AND the peripherals, so the guitar, the dj-set, the drum, whatever, and the experience was absolutely fantastic. Great fun, great music, etc.
But then the instruments would break. A button would stop working, or your hits wouldn’t register, and that kind of hardware failure would end in you not being able to play the game as intended, and thus you not getting the scores you deserve.
So, now you had a great game, but a broken instrument, and nobody is gonna buy a new plastic instrument every 3-6 months in order to keep playing the game.
A solution would have been to release better quality instruments (obviously), at a slightly higher price, so you could have kept the new games coming and the genre alive, but sadly, that didn’t happen.
Bust a Groove, Gitaroo Man and Parrapa the Rappa were such good games. Neither needed any extra peripherals

Player 2's long-form feature about kids and video games continues with a look at introducing toddlers to games for the first time.

Music rhythm games dominated the video game market in the mid-2000s. Unfortunately, the genre would fall from grace shortly after finding success.
More like faded away than failed. Failed implies it was new and didnt take off... that is not the case. Rhythm games were hugely popular but the lights dimmed and the show is over.
You would think the current situation would cause a resurgence but im actually seeing more people picking up real instruments and learning to play. My son is one who started out on GH and now he plays real guitar.
I lost interest when they stopped allowing you to use the controller to play with, just couldn't get into playing with the guitar.
Not the sole reason, but over saturation by Activision releasing 5 GH games in one year, charging full price for all of them while only Metallica and GH5 were worth it.
I dont think these games failed at all. People aren't going to keep buying games and peripherals over and over. All songs need to work on either rockband or guitar hero thru updates. Guitar hero live was actually good but rockband with all its songs and same equipment killed it.
I'm sure part of the reason they faded away, at least over the long term, was that you couldn't download them digitally.
