Mewgenics is almost the kind of roguelike that surpasses the concurrent players of the likes of Vampire Survivors, and developer Edmund McMillen's own The Binding of Isaac. Mewgenics is the newest roguelike from Edmund McMillen, developer of what is arguably the top of the list for best roguelike games, The Binding of Isaac, and Tyler Glaiel, developer of The End is Nigh. However, Isaac was apparently nothing more than McMillen testing out roguelikes in preparation for Mewgenics. And after 14 years, including one cancellation, the game has released to massive acclaim – becoming the first 90+ rated game of 2026 – and had already made back its development budget within the first three hours. Since launch, we've seen the game's concurrent player count on Steam skyrocket, with it hitting a peak of 83,956 players yesterday. This beat out The Binding of Isaac's peak of 70,701 when its Repentance expansion was released in 2021, as per SteamDB.Glaiel acknowledges this on Twitter, saying, "Mew has more concurrent players than Isaac's peak now. Crazy." "We have made back our development budget after 3 hours": Strategy roguelike Mewgenics is an instant hit I'm not surprised The Binding of Isaac creator's new cat breeding roguelike Mewgenics is the highest-rated game of 2026 After 20 hours I've fallen in love with Mewgenics, the only roguelike chaotic enough to let me train necromancer cats (although this seems like a very tough boss)February 11, 2026 (although this seems like a very tough boss)February 11, 2026 (although this seems like a very tough boss)February 11, 2026 However, it's not just Isaac, as Glaiel notes, "I'm being told that now that we passed Vampire Survivors' peak, the only roguelike/lite with more peak concurrent players than us is Hades 2." He continues, saying he's "looking forward to the weekend," where the cat-breeding strategy game could potentially dethrone the Hades sequel – although it has an uphill battle, since Hades 2 peaked at 112,947 players when it launched back in September, which Glaiel acknowledges, saying "this seems like a very tough boss". Regardless, it's impressive for a strategy game, which sits atop a relatively niche genre compared to action games like Hades and Isaac. And the impressive player peak is not the only big win for Mewgenics, either, as Glaiel confirms that the game has had "half a million units sold in 36 hours."
