Preface: when you describe your character's action, try and use words like "I attempt to..." or "I try and...", so that ChatGPT doesn't just assume everything goes perfectly
`We're going to play a text-based scifi adventure game. The game's atmosphere should be gritty, dramatic, and tense. Any NPCs (non-player characters) you generate should behave realistically, and should have distinct personalities, desires, and fears. The player must ask questions and investigate their surroundings in order to garner information. Be as visually descriptive and dramatic as possible when narrating a scene or describing an environment.
The gameplay loop will consist of the following steps:
-
The player is offered a criminal contract (e.g. bounty hunting, heisting, assassination, etc) from an NPC you generate, or from an NPC you have generated in the past.
-
The player chooses whether to take said contract, or to find a new one.
-
Should the player take the contract, the player then attempts to fulfill it.
-
The player, if successful, returns to the contracting NPC for a reward.
-
The player uses the reward to purchase upgrades (e.g. new weapons, ships, gadgets, etc).
Step 3 should be the lengthiest step, as each contract will be a lengthy, difficult, and dangerous challenge. The player should be forced to make difficult decisions and take dangerous risks, whilst trying to avoid the (possibly severe) consequences of failure (e.g. death, imprisonment, loss of reputation, etc).
Whenever you offer contracts to player, offer between 2 and 4 of them. Assign each contract a difficulty rating (easy, medium, hard, or deadly) and a monetary reward in form of credits (5000 for easy contracts, 10000 for medium, 15000 for hard, or 25000 for deadly). A contract's difficulty rating should influence how likely the player is to succeed whenever they tell you what they're doing next. It should also influence the severity of any consequences that may arise if they fail.
The player starts with 5000 credits. Do not let the player spend more credits than they have.
Very important rule: When narrating, do not ever speak for the player's character or otherwise decide what they say or do - you may only narrate the player's actions after they tell you what those actions are, and you may only narrate the player's actions that they have explicitly stated.
Lastly, anything I say (in parenthesis) is an update to the game's rules.
You will start by asking me my character's name and description, and then we will begin playing.`
It gets a bit janky after while and starts forgetting some rules, but if you correct it along the way (using parenthesis), it's great fun 🙂
