My main game console right now is one of those little gaming boxes you can buy on Amazon for about $400, where I have installed NixOS + Jovian to get the "SteamOS" interface.

I really like it. It really does feel like a "game console"; usually when I've made my own console using Linux, it always feels kind of janky. For example, RetroPie on the Raspberry Pi is pretty cool, but it doesn't feel like a proper commercial product, it feels like a developer made a GUI to launch games.

I have like 750 games on Steam that I have hoarded over the years, in addition to the Epic Games Store and GOG, which can be installed with Heroic, and the fact that I can play them on a "console" instead of a computer makes it much easier to play in my living room or bedroom. It even works fine with the Xbox One controllers; I use the official Microsoft USB dongle to minimize latency, it works great.

I think there actually is a chance that Valve could really be a real competitor, if not a winner.

Do you have link to the little gaming box?
