It still feels like it should be orders of magnitude less. For example, if each piece of cheese has an ID number that maps to cheese, an ID for what area it's in, three coordinates for where exactly it is, and maybe a few more variables like how much of it you've eaten. Each of those variables is probably only a couple of bytes, so each item is probably only 20B or so, which means that even if you interacted with a million different items and there was no compression going on then that's still only 20MB of save data.

Bold of you to assume the data in save files is packed binary and not something like JSON where { "x": 13872, "y": -17312, "z": -20170 } requires 40 bytes of storage.

Agreed. JSON solves:

the 'versioning' problem, where the data fields change after an update. That's a nightmare on packed binary; need to write so much code to handle it.
makes debugging persistence issues easy for developers
very fast libraries exist for reading and writing it
actually compresses pretty damn well; you can pass the compress + write to a background thread once you've done the fast serialisation, anyway.

For saving games, JSON+gzip is such a good combination that I'd probably never consider anything else.

protobuf does all of these (well, except compression which you dont need)
