The thing is, it does not have to be massive or sell a million copies. From my perspective, it only needs to sell one copy (to me). If the art is AI even if the plot is AI, I don't much care. I really don't care one way or the other if the art is 100% AI. I don't care if the inventory system was developed by AI. In a future gaming utopia (for me) I would sit down at my console and just describe the game I want to play and AI would build it on the fly for me. I might pay hundreds of dollars a year for such a capability. Perhaps thousands if it truly worked.
I know than many people got irritated by nvidia's DLSS as AI slop but I could not care less. If it means that smaller studios can make games that I might like I say bring it on. If someone will not purchase a AAA game because it has an AI smell to it then I guess that is their prerogative. Seems to me to be cutting your nose off to spite your face though.
