Steam Deck runs on their Linux-based Steam OS, so you will have to consider this list of compatible games before plunking down $399 for this device. Of course being that this is Windows compatible hardware you could always just install Windows 11 and Steam, enable Steam’s launcher and have access to Steam’s entire library of Windows compatible games instead.
