i think this is a super interesting idea with lots of potential. reminds me of History Respawned, which is about how certain games choose to depict historical settings, but also just an excuse to discuss the actual historical settings at length (w/professors and experts on the topic, sometimes straying entirely from discussion of the game). i really like this idea of pulling from something that is vague and maybe even accidental and reading more into it, breathing life into it by connecting it by force to other media and the real world at large. it’s a fun mental exercise! i think it would be even more fun if you did it to games that have a less directly archaeological vibe, like idk Noby Noby Boy, Sonic Adventure 2, or the city around a Wipeout racetrack :P
it would be even more abstracted/weird if you examined games you are unfamiliar with as games, so you could freshly look at them as artifacts, specially with games like Skyrim where there are mods that allow you to roam the land as a disembodied ghost-observer and you don’t even have to play the game.
