They also offer the Steam multiplayer backend, workshop, and Steam’s social system which is becoming enticing again given Discord’s latest behaviour.
GOG’s gimmick is no DRM, Itch.io has the cheapest self-publishing costs, and Epic has… well I’m not sure really, but the other two have their place, but it’s no coincidence Steam is the biggest.
Epic does sales where they release free games periodically. It’s great for people who like cloud gaming like Geforce Now.
I claim the free games and occasionally play a few through Heroic, but I have never and probably will never spend a dime there because everything there is a net negative:
- no Linux support, even for games with Linux builds
- same prices as pretty much everywhere else
- no unique features, and lacks many features compared to Steam
Pretty much the only reasons imo to use it are Fortnite and free games, and I don’t need an account to claim and play free games. So since I don’t play Fortnite and have forbidden my kids to play it, EGS has nothing to offer for me.
