Sea of Stars was like .. mid-tier (I did a review last year: https://battlepenguin.com/gaming/sea-of-stars/ .. did enjoy it, with caveats)
I can see AI helping with indie RPGs (game art is hard), but in my head, some of the best indie titles have been in the action genre: Hotline Miami I/II, Bastion ... or the gritty puzzle genre: Gris, Limbo/Inside, Planet of Luna, Far Lone Sail.
Narrative games and visual novels would benefit no-doubt, but you'd also get a lot of slop and a whole reviewer/curation industry. But action games still require a lot of fine detail work. Even with that, I still think most people would desire the "real" stuff, like Star Trek and not wanting replicated food.
I bet we'll see a scandal in the next 5 years where an indie title (like Coffin of Andy and Leyley sized fanbase) gets huge and then it's revealed all the art (maybe even the dialog) is LLM/ai-art based. That would be :gummypopcorn:
