Steam with a controller on your TV just isn't nearly as nice. I set it all up once (PITA on its own there) a few months ago after the steamdeck hype to show my wife some of the other games available in the world. It was kludgy at best and buggy at worst with some games.

I say this as a primarily 95% 3+ decade PC gamer. The other 5% goes to Nintendo exclusives such as Zelda or Mario.
