Too much too fast

If they had spaced it out to once a year or maybe a main title once a year and a side/band title in the middle of the yearly release then it could've stuck around

But they also had other issues, like the fact the games w/ guitars and band sets took up valuable floor space in retail outlets. So stores mightve eventually started to quit carry them at least in anything more than one or two at a time, regardless it the standalone games sold well or not.

Also by 2011 most people who were interested already bought in and were probably as good as they were going to get at the games.

There's still a fairly decent sized community of people on youtube and twitch that follow Guitar Hero and Rock Band though most channels play Clone Hero now(same exact concept, just in PC).
