Valve's new Steam revenue splits favour big-budget games, and indie devs aren't happy

If a game makes more than $10 million, developers get to keep a bigger cut of any extra earnings.

Valve has changed the way it shares revenue with developers on Steam—and it's good news for games that make a lot of money. Currently, revenue for Steam games is split 70/30 between the developer and Valve. But from now on, Valve will only take a 25% cut of any earnings over and above $10 million, and only 20% of earnings beyond $50 million. The first $10 million will still be split 70/30, and the change will impact any revenue earned after October 1 this year. 

In a Steam post, Valve said the change will help "developers of big games", which will in turn benefit the entirety of Steam because of the "positive network effects" those developers generate. But some indie developers don't see it that way, and have branded the move a "slap in the face" to smaller companies that will never reach the $10 million threshold.
