The Epic Games Launcher is so far behind on features compared to Steam it’s not even funny. Epic chose not to try and compete with Steam on that front and to try and force users onto the platform with exclusivity deals and sweeten the deal with free games.
The one user-centric killer feature Epic has in their stack IMHO is the built-in multiplayer crossplay. Except it’s not even exclusive to their store ironically (you do need an Epic account for it though).
Ouch. Right in the furniture.
