15 years after the original version released, The Binding Of Isaac: Rebirth has hit its highest-ever player count thanks to a massive discount.
Earlier this year, indie developer Edmund McMillen released his latest roguelike Mewgenics, which proved to be a massive hit. Not only is it one of the best games of 2026 so far, but a shout for being one of the best roguelike games of all time, and its numbers reflected that. It became one of the most-played roguelikes in Steam history in terms of concurrent players, beating out McMillen's own The Binding of Isaac, which is one of the best roguelikes ever in its own right, even if it was apparently nothing more than McMillen testing out the genre in preparation for Mewgenics.
