Just get a Steam Deck, and add a hub and wireless controller.

Oh, but it won’t run full-detail AAA releases at 4K? Nothing cheap will. That is exclusively the domain of consoles, earned through direct-contact optimization with developers. That’s still enough horsepower for the thousands of great indie games on Steam, many of which are simple enough to run fine on a midsize TV on the small Deck CPU.

Basically, if someone is adamant about running high-detail games on their TV using Steam, they’re already a niche enough market that it really doesn’t make sense to build up a single SKU for them and hope for bulk manufacturing savings the same way you could for consoles.

It’s probably better off for developers to keep targeting the Deck as a general metric point anyway. The especially good news there is, once devs do that, Linux desktop gamers benefit anyway.
