For this reason I'm SO into weird ROM hacks of popular games. I love love love seeing what one person thought would be cool to add to this established creation and how they went about doing it. I even love when they have terrible writing because that tells me something about the creator

And ROM hacks are one of those fun bits of media where there's no money to be made from them, it's all work done out of love for the source material or the ideas the creator is adding. Which is the very opposite of the objective with pretty much every AI-based creation I can think of.
