This is needlessly pedantic. When people say “physical copy” they are talking about a physical, individual storage medium with a game on it that you can trade/sell/lend/etc. and give full transfer of the license contained on it. My hard drive is useless to you if all my games are bought via the Microsoft store and you can’t access my account. My halo 3 disc will work on any Xbox 360/Xbone/XSX for anyone every day. Is the distinction clear now?
