Epic Games store is getting pretty competitive,
Steam takes only 30 percent cut of revenues from games on its store. That has changed to going down to a 80-20 split that make more than $10 million. And Epic Games Store offers a 88-12 split.

“Epic’s generous revenue terms are a game changer that will allow publishers to invest more into content creation, or pass on savings to the players,” Dr. Klemens Kundratitz, chief executive officer at Deep Silver, noted in a press release sent to GamesBeat. “By teaming up with Epic we will be able to invest more into the future of Metro and our ongoing partnership with series developer 4A Games, to the benefit of our Metro fans.”

if Epic Games’ store is able to push foward, it’s because of the success of Fortnite that made the Epic Game’s launcher one of the most popular.
