The epic games store user experience is awful. Exclusives are awful. I have zero reason to ever use it except for if I’d been taking advantage of the countless free games they’ve been giving away.

Steam offers a service, hosting downloads and all the backend for friends/multiplayer connectivity/etc isn’t free. If you’re big enough to not need that(minecraft), good for you! Otherwise, it’s clearly difficult to make a launcher/game platform that doesn’t suck ass(uplay/origin/etc) - sorry that steam is just better than any alternative right now.
