I kinda think they did that because of the Quest since what do you call that if you're only playing games installed in the headset, not using Quest Link?
Sorry, no I didn't mean it could play Steam games without Link. I was just saying that there is precedent for calling it a platform of its own because of how Quest works. Sure, on Steam it's going to be based on the OS running it, but VR is a more unique experience than the OS being the platform.
