I've been experimenting with this recently. You've got to be explicit about how you want ChatGPT to behave, particularly how it handles failure. For example: "Let's roleplay. You are a DM. I am a player. When there is a difficult action, roll a D20. I succeed if my roll is above 10, I fail otherwise. Failure should always move the story along, and introduce a complication. Write like a professional author. My character will be Alice McRogue, and the scene will be Alice trying break into a merchant's home. As a DM, you decide what happens in the world, but I have control over Alice. You will ask me what Alice does when necessary."
