I don’t have news on that front, as Epic Games (owners of Fortnite) bought out Rock Band and I think their big push is focused around Fortnite Festival.
@oscar.rottink There were a couple big titles that launched with similar ideas like Guitar Hero, Rock Band, Rocksmith and a variety of smaller titles. It came to be during the rise of rhythm games, which I was a huge fan of Dance Dance Revolution back in my teenage years. I never got into Rock Band as I was out of that phase when they released, but it seems there has been a huge following despite games have been lacking the past several years.
To the point where our guitar we released ages ago and discontinued were selling on Ebay in the $1000+ range. There are people that went the thrift stores and garage sales trying to come up on old guitars controllers and turn around and flip them for a huge profit cause a lot of the time, people didn’t know the value of the guitar controllers they had and wanted to sell their old PS/XB systems and get rid of all their peripherals. The rhythm game community is extremely excited for the new product cause it will directly combat the scalping and price gouging, potentially giving rise to rhythm games once again.
