Mewgenics Sets Record as Steam’s Most-Played Roguelite

Hold onto your catnip; a feline army has just toppled Olympus! The turn-based, tactical cat-breeding combat game Mewgenics, crafted by Edmund McMillen and Tyler Glaiel, has not only soared to the top of Steam’s charts but has also claimed the title of the most-played roguelike/roguelite game in Steam history, a record previously held by another popular title.

On February 15, Mewgenics hit an astonishing peak of 115,428 concurrent players, setting a new benchmark for roguelike and roguelite games and surpassing the former record of 112,947 concurrent players set by its predecessor. The Olympic-themed roguelite reached its peak on September 28, 2025, which, fittingly, was also a Sunday.

Edmund McMillen, known for his acclaimed action roguelike The Binding of Isaac, has outdone his previous record of 70,701 concurrent players, a milestone that stood since April 2021. Remarkably, just one day after its launch on February 10, Mewgenics had already attracted over 80,000 concurrent players.

This surge in popularity translates to financial success as well. On February 11, Tyler Glaiel revealed that Mewgenics recouped its development costs within just three hours, and by February 12, he announced on social media that they had sold half a million copies in a mere 36 hours.

While other celebrated roguelite and roguelike games, like the original Hades (54,240 players), Vampire Survivors (77,061), and Balatro (43,905), typically see player peaks in the 40,000 to 80,000 range, Mewgenics’s record stands out as exceptionally high. Even among cat-themed games, where Stray reached a respectable peak of 62,963 players, Mewgenics has nearly doubled that figure. It proves that anything is pawsible, especially with an endless supply of furry companions in the mix.

However, be prepared for a lengthy journey to uncover every secret the game has to offer, which will keep players engaged as we wait to see if Mewgenics will emerge as a contender for Game of the Year in 2026.
