The Epic First Run programme allows developers of any size to claim 100% of revenue if they agree to make their game exclusive on the Epic Games Store for six months.
After the six months are up, the game will revert to the standard Epic Games Store revenue split of 88% for the developer and 12% for Epic Games.
They offer a better cut than steam already. I don’t see why anyone would take this. Just put the game up both places. The only games this would actually work out for are the massive ones that people would seek out and download epic games bullshit for. Even then they’d likely lose so many sales it doesn’t make sense.
