I wonder if you could write a wrapper over Steam (and other services) that allows the same benefits of them, but lets you have your own store too. You'd have a launcher that could launch any game on your computer, whether it's on Steam or GOG or Itch or your own service, and a global storefront that merges them all (and prioritizes yours). Would that even be legal?

there have been plenty of meta launchers, but the social aspect and mods, etc are much more important than that and are never provided.
