@buru5 Of course the artist can preserve it. In the case of an individual, it's up to them.
And if it's a company, they will probably do so based on popularity (which the goal was to achieve in the first place, unlike maybe someone's personal project.)
Maybe someone's personal project will gain popularity 50 years later, like van Gogh's work. If they chose to preserve it and make it available.
But all that is not dependent on whether we, as consumers, own the games, right?
