The McMillen Effect: A 14-Year Wait Pays Off

We’ve been tracking Mewgenics for what feels like a lifetime—14 years, to be precise. For a project with that much development baggage, the risk of a "vaporware" stumble was real. Instead, Edmund McMillen and Tyler Glaiel have delivered a bona fide monster. The commercial impact was instantaneous; McMillen confirmed the game earned back its entire development budget in just three hours. That isn't just a successful launch; it’s a masterclass in leveraging indie goodwill and a "cracking game" to bypass the traditional marketing grind.

Shattering Roguelike Records on Steam

The raw data from SteamDB is frankly staggering. Just five days post-launch, Mewgenics clocked a peak of 115,428 concurrent players. To put that into perspective, we looked at the heavy hitters of the genre. The original Hades peaked at 54,240, and even the massive Hades 2 launch topped out at 112,947.

Our take? Surpassing both Hades titles in concurrent player count is a massive win for a game that "didn't want to play it safe." While the Hades franchise might still hold the crown in other metrics, Mewgenics has officially set the new ceiling for what a roguelike can do on Steam at launch.

The Critical Breakdown: Good vs. Great

While the player count is at an all-time high, the critical reception shows there’s still some room to grow if it wants to reach the "Overwhelmingly Positive" status of its peers. Here is how the numbers stack up:

  • Mewgenics: 89 Metacritic | 89% Steam Positive
  • Hades 2: 95 Metacritic | 95% Steam Positive
  • Hades: 93 Metacritic | 98% Steam Positive

We don’t put much stock in Metacritic averages alone, but the Steam sentiment is worth noting. An 89% rating is impressive, but it sits just shy of that coveted top-tier tag. It’s important to remember that these numbers only reflect the Steam ecosystem—they don't account for the console crowd—but the momentum is undeniable.

Is It Worth Your $27?

If you have any history with The Binding of Isaac or Glaiel’s previous work, this is a no-brainer. At $26.99 / £22.49, we’re looking at a price point that’s roughly "the price of a couple of coffees." For a game that lets you breed cats and make pacts with Athena while pushing the genre's boundaries, you can't really go wrong. If you haven't jumped in yet, the stats suggest you’re in the minority.
