Even with the importance of physical media ownership in the current era of digital product ephemera, it’s often unlikely your PC will actually be able to play the CDs, DVDs or Blu-Rays you have around the house. Internal disc drives aren’t common amongst desktops or even laptops anymore, so your only recourse is often an external drive.
One Steam Frame user was hoping to connect his own detachable disc drive to watch movies and play Need For Speed Carbon (valid!) using the headset, which can run both VR and ‘flat’ games without a separate PC, but found that the Frame lacked the drivers to read a disc. In a very earnest community post, user Aiodensghost lamented that this fact “KILLED MY ABILITY TO INSTALL MY ABANDONWARE FROM 2006. You don’t sell NFS Carbon anymore (fuck you very much EA) […] May I PLEASE have the ability to use an optical drive?” So polite!
