To this day, thousands of people still play Rock Band 4. Although precise numbers aren’t available, and the total is a far cry from the heyday of the iconic franchise, you could still theoretically find a handful of online lobbies at any given moment.
Based on recent Reddit threads, it seems that there are always new people looking to form a squad dedicated to playing regularly. Recently, with the release of PDP’s Riffmaster — one of the only guitar peripherals released in the last decade — the number of available players has likely grown.
According to Billy Brisebois, who oversees global brand and product marketing at PDP, the peripheral was in development for over a year. During that time, PDP gathered feedback from people who were still playing Rock Band 4. (Polygon)
