Mewgenics DLC is coming, but Edmund McMillen says he and co-creator Tyler Glaiel want to take a few months to 'fully understand what people really like about the game' before they start on it
Mewgenics, the cat-breeding brawler from Edmund McMillen and Tyler Glaiel, is a big game. Senior editor Robin Valentine wrote in his review (92%, by the way) that "after three weeks and over 100 hours of Mewgenics taking over my personal life, it's still surprising me every run." In case that's not sufficiently convincing, McMillen himself said it will take most players more than 200 hours to "beat the game," and more than 500 hours to see and do it all.
That's a whole lotta playtime, enough to keep most people going for weeks...
