It is incredible how much the other stores fumbled the implementation. As a rule, Epic, Origin, etc apps were terrible. Laggy, bad UI, sometimes difficult to even complete a purchase.

Yet it always felt like web developers pumping out another half assed Electron platform. The Steam store must generate billions in revenue -put some real manpower behind the engineering.
