"What matters is that the creator was satisfied with what they accomplished" yes but that mainly matters to the creator, there is no objective meaning to what "matters" in art
If I showed you my story that's been in the works, and then showed you Shakespeare, how would you judge which one is better? If me, the creator, am proud with what I made and believe it to be better, than all other opinions are invalidated.
For projects with no director- it belongs simply to whoever created it. That can be more than one person.
Stuff made just to show others? I know what it's like. I'm an entertainer. A people pleaser at heart. Nothing in this world feels better than knowing I entertained or cheered someone up. It's fine- but people can't criticize someone's work just because it doesn't suit them flawlessly.
Devs that are hired to make someone else's stuff are tools. Just- tools with feelings.
They can throw suggestions out- but those are utterly worthless if the one in charge says no. Developers have fixed goals. They're not making anything on their own. They're creating what someone else told them to.
The creator made a duck- the creator hired people to make more of the same duck. Those hirees aren't being artistic in anywhere near the same way.
"If me, the creator, am proud with what I made and believe it to be better, than all other opinions are invalidated." that's the thing, that's to you only, there are no objective correct opinions, opinions just have differing amounts of weight depending on the person
It really just depends on if you're doing it for yourself or not. I mean... I have some art I don't show to anyone else. Then I have the art in my art dumps- people only got to see that art 1. because I deemed it worthy of representing the actual image I was going for and 2. because I like these people.
If I didn't post it, people couldn't have told me it was good or bad- but either way, it represents the same thing.
An artist that only makes art for other people- well that would be similar to a developer, except that that artist is actually making 100% of it. They're making it specially because they want whoever to like it. That's much different.
