As a game developer I’ve always been saddened by the ephemeral nature of games. It seems impossible to make a game that would last 20, 50, 100 years. Books, paintings, even movies have such an advantage
But the comparison isn’t entirely fair. If you were to compare a game to a concert or a festival, as an “ephemeral cultural performance by a large group of people” you could also argue that a festival lasts for a set number of days, until it’s gone, forever.

Software archival is not that hard unless the ecosystem is specifically designed to prevent it.
N64, GC, Wii, NES, all of their games still run on modern hardware.
Webapps will probably fair pretty well too.
As does Win32, Wine, Proton.
Your choice of stable platforms is actually pretty big in the game world! Pretty much every platform except native mobile!
