Just FYI: I've had a really good experience with Heroic launcher. Use for playing those Epic freebies I've accumilated over the years, and has been pretty solid, almost Steam-like experience.
I second this. I would use an epic account like a burner account and just get all those free giveaways. Heroic works for the Amazon prime games as well. I played a little bit of trek to Yomi the other day because I had a friend mentioned it was free on epic and I didn’t even realize I already had it.
