“…their useless proprietary launcher.” Steam is by far the least useless launcher out there. Steam has so many incredibly useful features such as remote play together, community controller layouts, the workshop, cloud saves, family library sharing, etc. Not to mention that they continue to keep adding new features that no other launcher is even close to having such as the new game recording feature that is currently in beta.

Sure, Valve charge a pretty decent amount to game developers for the sale of a game, but they provide a load of features in exchange.
