It’s about a decade old but it’s the couch version of Steam, completely navigable with a controller. If you’ve ever seen a Steam Deck, that’s just Big Picture Mode.
I believe Steam Deck got a completely new interface that also later replaced the old Big Picture mode. It also of course has a more complex setup, since it’s not running in a desktop environment, but that’s more about the overlay and running games.
