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.
Game dev here, please stop licking these dirty boots. 99% of the money goes way up the ladder and into the heads of people with 0 interest in making fun games
