Valve wants to make Steam more alluring for large developers, and it's willing to give up a slice of the pie to make that happen. The company has revised Steam's Distribution Agreement to give its most successful publishers a larger cut of their revenue from games, add-ons and in-app purchases. Any game that has earned over $10 million on Steam since October 1st, 2018 will provide developers a 75 percent cut of future revenue rather than the usual 70 percent. If they make at least $50 million, they'll take home 80 percent on any subsequent earnings. A blockbuster hit could easily generate significantly more cash.
