Good for them, it's nice to see some management that hasn't totally bought into this "no workers, only subscription AI bots" vision of the future that so many tech CEOs are selling.
Personally I would never pay for tabletop miniatures or lore books generated by AI. It's the same core problem as publishing regurgitated LLM crap in a book or using ChatGPT to write an email - I'm not going to spend my precious time reading something that the author didn't spend time to write.
I am perfectly capable of asking a model to generate a miniature, or a story, or a dumb comment for reddit. I have no desire to pay a premium for someone else to do it and get no value from the generated content - the only original part is the prompt so if you try to sell AI generated "content" you might as well just sell the prompt instead.
