Digital games are a bit different, since you’re actually downloading the game files. Games can always be modded to remove DRM, or the systems they run on can be modded. See the 3DS as a good example of the latter.

The best equivalent is game streaming. You never have the game’s data in your possession, and a game can be pulled off the platform at any time. Even then though, you’re usually paying for the service, not individual games.
