There's a lot of truth in the idea that modern games won't be fixable in 30 or 50 years. Proof? Just look at any modern device - cars, refrigerators, computers, etc. They are built to be unrepairable, both through parts that are all but impossible to re-create and through software brick walls. In 2073, absolutely no one will be restoring 2023 Hyundai Elantras.
The average person 50 years ago would throw up if you tried to sell him a product that he couldn't repair. But, people have been weaned off of that idea over the decades....now, no one knows how to anything but order a new one off Amazon.
