The Cat-Breeding Brawler is an Instant Heavyweight

After a staggering 14 years in development limbo, Edmund McMillen’s Mewgenics hasn't just arrived—it has absolutely detonated on the charts. We’ve seen many long-awaited indies stumble at the finish line, but McMillen and Tyler Glaiel have pulled off a rare feat: hitting the #1 Steam seller spot and clearing their entire development budget within three hours of launch. Selling over a quarter-million copies in less than a day is the kind of momentum that turns a "weird cat game" into a generation-defining roguelike.

Our take? The numbers don't lie. Between the 92% critical reception and the immediate player buy-in, Mewgenics is proving that the "Binding of Isaac" formula wasn't a fluke—it was just the beginning. The game is already being described as a sprawling, ridiculous experience that transcends McMillen's previous work.

Prepare Your Schedule: The 500-Hour Grind

If you were looking for a quick palette cleanser, look elsewhere. This is a game designed to take over your life. McMillen has stated that while "beating" the game might take a standard 200 hours, completionists looking to see and do everything are looking at a 500-hour investment. With 280 Steam achievements at launch, the depth here is staggering.

Senior editor Robin Valentine noted that even after 100 hours of play, the game was still throwing surprises his way. For the min-maxers and roguelike fanatics in our audience, this is the "forever game" you've been waiting for. It’s not just about the length; it’s about the sheer variety of builds and runs that keep the meta fresh.

DLC is Coming (Eventually)

Despite the base game being massive enough to last most players through next year, the devs are already fielding questions about what’s next. McMillen’s strategy for DLC is refreshing: he wants to wait.

"We have a rough idea of something small, like a few more classes and more areas," McMillen noted during a recent AMA, but he emphasized that they won't start work until they "fully understand what people really like about the game."

The "McMillen Time" Factor

While the goal is to start on DLC in a few months and potentially release it a year after that, veteran gamers know the drill. McMillen is famous for announcing cool concepts and then taking his time to polish them to perfection. Given that Mewgenics was originally teased back in 2012, we suggest enjoying the 500 hours of content currently on your plate and not holding your breath for an expansion before 2027. The wait will likely be worth it, but the base game is already a feast.

Technical and Strategic Depth

For those currently struggling in the trenches, the game is proving to be as brutal as it is deep. Whether it's figuring out how to beat Dybbuk or surviving the Heat Wave in the desert, Mewgenics demands mastery of its systems. This isn't just a cat-breeding sim; it's a tactical gauntlet that rewards players who dive deep into the mechanics and ignore the "outside world" for a few weeks.
