The current generation of consoles can’t run them locally, so the developers would have to run the models for the customers. Considering most game developers (including Rockstar) don’t even have dedicated servers for multiplayer, that’s probably too much to ask.
I think Elder Scrolls 6 has a higher chance of implementing it, only because Microsoft owns Bethesda and also has the OpenAI partnership. Microsoft also has a history of supporting game devs doing stuff with Azure.
I’ve dabbled with adding an LLM to OpenMW, and I think there’s potential there. But I also think it could get very expensive. Maybe by the time ES6 comes out, that won’t be the case.
You don't need to be able to run the LLM locally yet in order to benefit from this, nor do you need to have your own robust game server.
It definitely needs to be done thoughtfully to avoid creating plot holes or messing up character personalities, but especially games like Stardew Valley I think you could get some super interesting storylines going. Embed the important characteristics and personality into the prompts, to keep the AI in line, but let it do it's thing.
To prevent inappropriate things from happening, the players cannot try to jailbreak the AI because player inputs never enter prompts, instead all stories are linear and pre-generated.
I don't think it does missions, but the conversations are pretty neat.
(It was used to generate x number of possibilities, each were human vetted and ran by the LQA and FQA teams.)
Cannot mention the product name though sorry :s
Edit: not in a live environment, just as a 'generator' though
