The repetitiveness in video game dialogues is a feature, not a bug. Amongst other things, it allows you to re-retrieve information and hone in faster on what’s story and what’s relevant progression. Having each character invent their own inconsistent sloppy backstory whenever you talk to them is not a positive, it’s not good immersion when every character is a chatbot that can inadvertently give you story beats you shouldn’t be aware of yet or you missed some crucial bit of information but no one talks about it anymore (or worse, never did). In that world, those games would be made popular by people breaking the LLMs in funny ways, not the gameplay itself.
