This means you can't pass the game around to your friends or sell it afterwards, which completely ruins the purpose of physical media imo. I mostly play PC these days so this doesn't affect me, but it's a disappointing direction for console games. At least they could've used an empty disc that has proof of ownership.
EDIT: Bethesda has confirmed that only the PC version won't include a disc. Physical versions of Xbox will include a disc. Whew.
One that carried the game key, making it portabaly transferable.
Yeah, so the issue here isn't "omg how can they sell a case with no disk" it's "hey, I want to own my game", which is totally fair. Seems like people focus on the most superficial part of the whole issue, a literal shiny piece of plastic.
