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).
He’s well liked because he came from the trenches and has a good track record of knowing his shit. When compared with the likes of Kotick or Guillemot, it’s a breath of fresh air (despite being such a low bar). However as one of the highest execs in the entire gaming industry, this is the kind of stuff he does all year long.
Plus you know, his public-facing image is well curated and people like it.
