Yes, you can play Steam games with the glasses. To do this, connect the glasses to a VR-capable PC using a USB-C cable, activate Oculus Link and start SteamVR on the PC. The glasses are then recognised as a VR headset and you can play SteamVR games such as "Half-Life: Alyx" or "Beat Saber". Alternatively, you can also use the Steam Link app to stream games wirelessly from your PC to the glasses, provided your PC and network fulfil the requirements.
