When Epic announced that Metro Exodus would be a year-long Epic Store exclusive, it was close to release and had already been taking pre-orders on Steam. At the time, I said it was an act of war. 

A panel of Epic Store leaders were asked during an Epic Store Q&A at GDC 2019 today if, given how much rage the move caused, they'd ever do something like that again. Steve Allison, head of the Epic Games Store, responded immediately: "We don't want to do that ever again."
