I am not going to blatantly support piracy of video games (Most of us work in the software industry, and most of us want to get paid for our work. Video games should be no different.), but I think it's clear that game preservation has some issues in its current state, and Nintendo is one of the worst offenders. Nintendo is a lot like Apple in this way. They see things in one way, and assume all consumers will happily…
Or just a hypothetical example: you bought a cool sandbox game in alpha and then some years later, some big IT corp comes around and requires that you now have to use their account system, hand over your data and agree to being tracked.
