I can play 60%+ of games on Linux because Valve cares way more than anyone else.
Big Picture works great for a console like experience far better than anyone elses.
Valve Controller let's practically any game under the sun be couch & controller playable.
Remote Play, then Remote Play Together, now Remote Play Tablet blow everything else out of the water.
I'm sorry the you doesn't meet your high pop culture desires? It feels much less glossy-plastic & more direct to me than Epic. That's just me I guess. The thing is, that is way way way way down my list of concerns. Steam is a technical juggernaut. No one else is even playing. Steam is super under appreciated. The lack of mainstream highly visible overwhelming successes doesn't bother me. Steam is innovating at the edge in radical ways, & they are always always always trying to spread the love, not steal the sunshine.
