Oh, I missed the UHD bit, right. Triple layer it'd cap at 20-25, yeah. Technically Switch carts were available up to 32GB, but I think like one or two games ever used that much, they were so expensive. That's where the partial download stuff comes in.
Of course for optical media the solution was always to ship multiple discs, because the smaller discs are so cheap. Or were. With most optical media manufacturing phased out who knows how expensive optical will become.
I am pretty sure that this honest leftist self-criticism thing is against online decency rules and I demand to see the manager.
