I agree with your sentiment that a creator should have control over their work. However. I do feel that an art piece which can only exist in one form is different from commercial mass media. Mainly because you start getting in to an “original vs a copy” territory. While I believe an owner of something should have control over copyrights…once someone legally owns a “copy” of something that copy should be theirs since the owner made the mass media thing for the public to consume I believe the public should, at some point, have a say in the future trajectory of the product, after all it is still the public who “decide” if a product is good and will be remembered, and they even “decide” the value of the product as well.
Art is usually only made for a select few to own…it is “artisanal”…meanwhile video games are made for a much larger group…
