It can; you have to buy the games on Stadia. _Hopefully_, there will be a way to export those licenses out of Stadia.

Can you think of any other system like that which allows you to export licenses to games? AFAIK, that's unprecedented in the industry, and explicitly against the contracts I've seen.

Edit: Steam will let you _import_ a CD key, but that's the closest I can think of, and there's no way to export once it's in steam.

When the Ultraviolet movie service shutdown they had some mechanism to prevent users losing their purchased content. I don't know how it worked exactly but ultimately it must have been some kind of license transfer. I don't think it's a huge stretch to imagine something similar being applied to video games.

Ultraviolet wasn't a service really AFAIK, it was a DRM scheme that brokered licenses to other services. those other services could continue running off of the cached licenses, but there's no way to re auth licenses for Ultraviolet works you have but haven't registered yet.

Yeah, I'd be surprised if they'd give anything more than a refund, and probably only a partial one. It isn't really practical to do anything else for a service like this.
