I agree, but I feel like pointing out that any game that was distributed without DRM or that was successfully 'cracked' by pirates can also be found on archive and therefore might be carried over to future generations. Physical media isn't the only way.
The real risk, IMO, is live service games that don't function at all without the server being online. There are games where fans have reverse-engineered and made their own server, but there are definitely ones that will slip through the cracks and be forgotten too.
