This is why Steam is as popular as it is, they just release features that people like. Sure GOG doesn’t have DRM and Epic Games gives a bigger share to developers but Steam gives players what they actually want.
not just features for the average consumer, but also a plethora of tools for developers. But then you’ll see some airhead keep saying about the 30% cut that steam takes.
Steams custom controller profiles alone used on Steam Deck are killers for me. Nothing else amounts.
Steaminput is a massive deal, it supports gyro, remapping, profiles, and extensive customization. XInput can’t compare and the epic games store relies on developers for everything. That’s the reason why I will always pick a Steam Controller over an Xbox controller.
XInput can’t compare
XInput is X11 API and SteamInput can be used through SDL or directly.
GOG has DRM for many titles: see Galaxy. As I understand it, it isn’t as pervasive as Steam, but is necessary if you want multiplayer on many titles or care about extras like achievements.
Achievements or multiplayer matching not being implemented in the game itself isn’t on GOG. They still allow you to download and launch any game you’ve bought, without even requiring galaxy.
Also lesser known is the fact that there are DRM-free games on steam. Download them once, you can play without having steam running or even installed. Using a client to download isn’t inherently DRM either.
Cloud sync also requires the drm, but the advantage that gog and itch have over steam is that for most games you just get the executables and you’re good to go.
Tbf to cloud sync, nothing is stopping you from using your own backup/restore service with your drm-free titles compared to the other features that Galaxy offers.
