The Binding of Isaac
Recently, a leak in the Steam API allowed everyone to see some of the most accurate player counts available to date. While the information presented does not fully represent hard sales data, it does count every player that has played a game with achievements more than once on Steam.
While looking through the list we thought it would be interesting to see exactly how well indie games were doing compared to major releases. And, as it turns out, there are a lot of indie games that are holding their own.
Starting things off at nearly 7.2 million players is The Binding of Isaac by Edmund McMillen and Florian Himsl. The game originally released on Steam in September of 2011. With this information, we can surmise that the game picked up roughly 1 million new players each year since its release.
It’s also worth noting that these figures wouldn’t take into account the player count of The Binding of Isaac: Rebirth, the 2014 remake. Rebirth has been successful in its own right with 2,756,509 players revealed in the leaked data.
