Competition sounds great, so long as it has all of the following:

• Something better than steam input and the steam controller.
• Something better than steam vr.
• Something better than steam workshop.
• something better than proton
• Something better than steams friends/chat/activity interface.
• Something better than the steam overlay.
• Something better than big picture.
• Absolutely no exclusives, and no deals forcing developers to use it.
• A nicer store interface than valve, with better community pages, curator pages, discussion pages, etc.
• An equivalent to steam fest with a strong demo scene.
• Something better than remote play together

This is of course also ignoring just how efficient, clean, customisable and ergonomic the steam interface is compared to all competition

Oh wait! That doesn't exist. All we need is some way to guarantee valve doesn't become public.
