Havent games been quasi digital for a while now? Like the disc or cartridge is just a key to download something.
No. I don't get how a lot of people got that idea either. Many games for the PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X | S are full on the disc. These systems pull the full game data from the disc and installs them onto the drive each respective system uses. This can be done 100% offline too. There have been a few physical releases where only part of the game was on the disc, and the other half requires a download. In those cases, you obviously needed the internet. I don't personally feel these are good releases. There has never been an instance (that I've heard, known, or seen that is) where the disc itself is just a key and nothing more (basically game key cards but instead of a cartridge, it's an optical disc). That would imply that such a concept predates the game key card logic, which didn't actually exist prior (doesn't make any sense either, that's a lot of wasted disc space for a key, especially if it's a Blu-ray disc). If there was an instance of a "physical" release for a digital version of a game, it was always a download code inside of an empty case.
So whoever, whatever, told you that the game discs were just keys, totally lied to you. Even back when physical releases existed for computers in the final days (2010-2013 era), the discs had the full game contents on the disc. Internet access was only needed for software activation, account creation and logging, and any updates for the software. That's basically what it is with physical media on consoles, aside from needing 50,000,000+ different launcher software, and potentially being locked out from activation when the services die off. The game discs house the full game, updates are fetched over the internet. The only exception to this, is if the game disc is reprinted as a revision of the game, containing the game and update contents all on the disc. This is common for game consoles.
What makes this very important:
- You don't need internet to install or run the game (aside from the game requiring account credentials, but that's a game problem, not a disc / cartridge problem).
- You don't lose access to that content once the services end entirely, unlike the digital version from the storefront that basically becomes inaccessible unless you hack your console and pirate.
- Using a hacked system, you not only can back your own discs / cartridges up, but you can create digital versions of your games converted from those backups. So if you are the type that wants digital convenience, you literally get the best of both worlds, with zero loss. Not even the dead service can stop you.
