Astcit 's talking about how modern pizza is a modded version of the ancient Roman panis focacius (precursor of sorts to focaccia) and developed over the centuries. It really extends even further back, but it depends how liberally you'd like to describe a flatbread with toppings as a pizza, since it's such a simple concept at its core.
It links into his point about how highly moddable games have staying power, whereas less-moddable games like CDPR's RPGs don't have
as much staying power (though I imagine they'll be considered beloved classics years from now due to their great stories and characters).
Not entirely sure if the analogy holds up in a gaming sense without emphasising the moddability itself? But say you invent a brand-new culinary delight today, let's call it
Pickled Ass Steak.
People are still eating pizzas of all kinds - different doughs, different toppings, different shapes - even now, vast centuries after its conception. This is largely thanks to the ability to mod pizza and keep the concept fresh and exciting (or more to the point, to customise it to an
individual's preferences). Will there be as many people eating
Pickled Ass Steak in the same number of centuries from now? That's more the point Astcit was making, so I think the food analogy still reinforces his point about Morrowind etc.
