I would argue UE5 enables and encourages bad development practices that lead to the unoptimized mess that "modern graphics" games are right now. Their work is cool, but so many games rely on temporal aliasing for in-game effects now, and UE5 is the common denominator.
Steam and GOG have a strong history and userbase. 0% commission is nice, but Steam in particular offers a world of more value than Epic Games Store, including but not limited to a usable fucking user interface (I use Rare to play my EGS library because it's so bad).
Steam games are DRM free unless you consider Steam itself a form of DRM. DRM is implemented by the developers of the game, not by the marketplace it's sold on.
And I find it strange that you think GOG has a better business model than Steam and will be more competitive long-term. Why do you think so?
There's no reason to trust random APKs for stuff like this anymore when Revanced exists to let you build the APK yourself right on your phone with only the patches you want. Highly recommend!
