I know about Heroic, but I refuse to support a company that is so much against Linux. They purchased Rocket League and took away the perfectly functioning Linux version back then (and made it unplayable for a while for me). Why would I pay Epic Games money, if they don't support Linux, while Valve actively pays developers to program and help the Linux world of sides?
I'm not interested into Heroic Game Launcher. It does not address the problems I have with Epic and does not support everything Steam has, when I purchase it on Epic Games.
