The digital landscape of PC gaming has been irrevocably shaped by Steam, Valve’s ubiquitous digital distribution platform. For nearly two decades, it’s been the primary gateway to a universe of
interactive entertainment, fostering communities, launching careers, and, most importantly, hosting some of the most beloved and enduring games ever created. But with an ever-expanding library and the ebb and flow of gaming trends, what truly defines “popular” on Steam?
