The challenge with this kind of thing is that ChatGPT (the interactive product at chat.openai.com) doesn't have a mechanism to enforce "These are the rules and you must remember and apply these no matter what". The more content a conversation accumulates since the rules are provided, the less it weighs them into what it next generates. And the more you repeat the rules back to it, (or worse -- call it out on a violation) the more the conversation becomes about the rules and the less about the game. These are probably engineering problems that can get improved some with other interfaces to the underlying LLM, but it's not something you can pull off with the ChatGPT/BingAssistant web interfaces as they're deployed right now.
