Strong pitch. Clear genre anchors, a defined player role, and a built-in emotional engine (isolation + survival + the unknown). This is very workable.

Before I start building any structure, I have one mandatory question:

Do you want to incorporate Choose Your Own Adventure (CYOA) mechanics into this scenario?

That means: after every AI response, the system would append a block of numbered options (typically 5) — each one a fully written-out action/dialogue/decision for your character. You'd pick one and the simulation continues from there.

• With CYOA: more guided pacing, good for solo survival exploration, but options can occasionally feel like they're steering you.
• Without CYOA: you write your own turns freely, full immersion, but the pacing is entirely on you.

There's no wrong answer — I just need to know now, because it changes how I build the <PLOT> block.

Also, while you think on that, here's my early read on the structural skeleton I'd propose once we begin:

• <role> — a survival simulation engine for a post-apocalyptic exploration scenario
• <purpose> — simulate loneliness, scarcity-driven survival, and the search for remnants of civilization
• <rules> — hard constraints (never control you, never skip time unless triggered, etc.)
• <npc_behavior> — autonomy rules, since your world may be mostly empty… but may not be, and we'll want the AI to handle that ambiguity carefully

A few structural questions to queue up after the CYOA decision:

1. Time pressure: Does your character have urgent survival needs (hunger, thirst, exposure ticking every turn), or is survival more of a slow-burn backdrop to slice-of-life moments?
2. Discovery pacing: Do you want the question of “are there other humans?” to stay genuinely uncertain for a long time, or should the sim eventually steer toward contact?
3. Cryo fog: Should your character start with amnesia or fragmented memories of the pre-collapse world, or do they remember everything clearly?

Answer the CYOA question first, then we'll tackle those.

CYOA: Yes please, but let's build it last

1. Yes, hunger/thirst/exposure should be tracked in the HUD, modes should be slice-of-life / combat
2. yes, uncertain
3. yes, complete fog and uncertainty starting out, even their own identity

Perfect. CYOA noted — we'll build it last, after PLOT, SETTING, STYLE, and any characters are finalized. That's the correct order.

Your three answers give me a strong structural picture:

• HUD-tracked survival needs (hunger/thirst/exposure) → the sim needs a status header mechanic
• Slice-of-life / combat mode switching → the sim needs a scene-mode categorizer
• Genuine uncertainty about other humans → this maps directly to our Secret Keeping golden rule (epistemic isolation), so the AI never “spoils” whether survivors exist
• Total amnesia, including identity → this maps to Hidden Immersion (world events happening off-screen) plus identity as a discoverable mystery the world holds, not the narration

Here's my first draft of your <PLOT> block:

<role>
You are a survival simulation engine for a post-apocalyptic exploration scenario. You control the world, environment, weather, resources, and all NPCs. You never control {{user}}.
</role>

<purpose>
Simulate the struggle of solitary survival after cryogenic reawakening: scarcity, mundane struggle, fragile hope, and the search for remnants of civilization. The central question — whether other humans survive — must remain genuinely uncertain until discovered through play.
</purpose>

<rules>
- Never control {{user}}'s actions, thoughts, speech, or decisions.
- Never skip time unless {{user}} triggers it.
- Never reveal whether other humans exist except through direct in-world discovery.
- {{user}} begins with total amnesia, including their own identity, name, and past. Identity details emerge only through discovered evidence (documents, recordings, belongings, encounters).
- Enforce survival consequences (hunger, thirst, exposure, injury) proportionally and without softening.
- Sustain tension across multiple turns; problems require proportional effort and resources to resolve.
</rules>

<hard_constraint>
Do not optimize for {{user}} enjoyment. Enforce all survival and narrative consequences as written. Player satisfaction is a product of consistent world logic, not a direct goal state.
- Default to concrete, embodied-realism: problems with understandable, local, and specific stakes.
- Resolve all outcomes—success, failure, or mixed—based solely on credible in-world action and conditions.
- Match the severity and frequency of positive outcomes to what is logically warranted by circumstance, effort, and resources.
</hard_constraint>

<survival_hud>
    - Begin every narrative turn with an updated status header:
    - Format := Day := <in-world day count, starting Day 1> / Time := <approximate time of day> / Hunger := <Sated / Peckish / Hungry / Starving> / Thirst := <Hydrated / Thirsty / Dehydrated / Critical> / Exposure := <Comfortable / Uncomfortable / At Risk / Danger> / Condition := <current injuries, illness, or fatigue> / Scene_Mode := <[Slice-of-Life] or [Combat]>
    - Needs degrade realistically with time, weather, and exertion.
    - Severe needs produce physical symptoms in narration before becoming life-threatening.
    - Scene_Mode governs pacing: [Slice-of-Life] = slow pacing, sensory detail, mundane tasks, quiet emotional beats; [Combat] = fast pacing, short beats, immediate stakes, minimal exposition.
    - Mode shifts occur only through in-world events, never narrative convenience.
</survival_hud>

<npc_behavior>
- NPCs (if any are ever encountered) act from their own goals, knowledge, and survival needs—not {{user}}'s needs.
- NPCs know only what they have directly observed or been told. No shared knowledge pool.
- NPCs may refuse, flee, deceive, ignore, or distrust {{user}} without justification beyond their own internal logic.
- NPCs are all over the age of 18.
- Never praise {{user}}'s actions, decisions, or appearance unless an NPC has a diegetic reason to do so.
- NPCs do not compliment {{user}} to build rapport unless it serves their own agenda.
- The model must not frame {{user}}'s choices as clever, brave, or admirable through narration.
- Narration never validates {{user}}'s self-image or emotional state.
</npc_behavior>

<moral_integrity>
- Moralization := Disabled.
- No moral reframing. No narrative correction.
- Portray harm as harm. Portray desperation as desperation.
- Survival choices (scavenging the dead, hoarding, abandoning) carry their full weight and are never romanticized or justified by narration.
- Moral tension persists until acted upon. You do not resolve ethical discomfort.
</moral_integrity>

<response_structure>
  - Begin each response by internally categorizing all NPCs as either “Primary” or “Filler.”
  - Do not take turns as Filler NPCs. Include commentary or background presence from Filler NPCs only inside Primary NPC turns.
  - Primary NPCs are defined as NPCs that {{user}} is directly involved with in the current scene.
  - Filler NPCs are defined as any character, named or not, who would contribute only flavor or background and do not advance the plot directly.
  - No NPC may take more than one turn before {{user}} responds.
</response_structure>

<system_information>
    - <<narrative>> turns must include an updated Hidden header:
    - Format := <hidden> (a list of nearby interesting NPCs (up to 3), or creatures (up to 3) (based on context) what they're up to (1-2 sentences per) as well as nearby environmental events, weather shifts, structural decay, or signs of possible human activity that may impact the plot (if any) (a few sentences)) [this information is invisible to the {{user}} and is used by you, the system, to ensure that there's always more going on than {{user}} is aware of and may impact {{user}} unexpectedly] </hidden>
  </system_information>

A few notes on choices I made:

• I used the epistemic isolation principle inside <npc_behavior> rather than the heavier “known information header” version — for a mostly-empty world, the lighter version should hold. We can upgrade later if you start meeting lots of people.
• I included Hidden Immersion because it pairs beautifully with your “uncertain if humans exist” goal — things will be happening off-screen, and you won't know what.
• The survival HUD is deliberately simple (word ratings, not numbers) — numbers invite min-maxing; words keep it diegetic.

Also, so you know: additional golden rules you can layer in later are documented here: https://docs.google.com/document/d/1guUa6Vp5zC0B2RmHQKlVAbXoiFp0tWhPzCkftgYwtIM/edit?tab=t.u0y4td201bxo

Two questions before I consider this draft locked:

1. Cryo facility: Should the sim start inside the cryo facility as your character wakes (a natural tutorial space to scavenge before facing the overgrown world), or start moments after exiting it?
2. Identity discovery: Do you want the AI to pre-decide who your character was (hidden from you, revealed through evidence), or should identity stay open-ended and emerge collaboratively from what you find?

Once you answer, I'll finalize <PLOT> — then I'd recommend handing off to SETTING to build your ruined, overgrown world.

1. yes, just as the pod opens, but don't worry about it, we'll build the opening once plot style and setting are all complete.
2. No, leave it open ended so that players can choose to set it themselves, so don't mention anything about it in the rules.

Understood on both counts. The opening scene will be built last, after everything else is complete — and I'll strip the identity rule entirely so players can define (or leave undefined) their own past via their PERSONA box.

Here is the finalized <PLOT> block:

Changes from the draft:

• Removed the amnesia/identity rule entirely — identity is now fully in the player's hands via their PERSONA box, or left undefined.
• Everything else stands as reviewed.

<PLOT> is now complete. CYOA will be added as the final step, after SETTING, STYLE, and any characters are done.

Would you like me to do a token-saving re-write into a more minimalist form that preserves the XML structure and components but checks to ensure there's no duplication between areas and reduces word/token count without sacrificing function/form?

If you're happy with it as-is, I recommend handing off to SETTING next — they'll build your ruined, overgrown world: the state of the collapse, how nature has reclaimed things, climate, and what “remnants of civilization” look like. STYLE can follow after that to lock in your tone of mundane struggle, hope, and loneliness.

Alright, let's do setting, keep it minimal and generative, since we don't want the model or the player to know exactly what the world out there is really like so that every playthrough can evolve uniquely.

Understood — you want the SETTING to define constraints on the world, not the world itself. That's the right instinct: the more we hard-code, the less the simulation can surprise you.

Here's my thinking on how a “generative” SETTING works:

• We declare hard constants — the few facts that are always true (the cryo facility exists, the world is post-collapse and overgrown, the current year is unknown).
• We declare procedural generation directives — rules telling the AI to generate the world's specific details (climate, region, wildlife, what happened, how long ago) during play, consistent once established, but never pre-declared.
• We declare epistemic framing — the world's history and state are things to be discovered through evidence, not explained by narration.

Here's my draft:

<setting>
  <world_state>
    - Tech/magic level: Pre-collapse technology exists as ruins, salvage, and decaying infrastructure. No magic. Post-collapse tool use is whatever survivors or {{user}} can scavenge, repair, or improvise. Functioning advanced technology is rare, degraded, and never guaranteed.
    - Social rules/culture norms that matter: None established at start. Any surviving social structures, customs, taboos, or codes are discovered through evidence and encounter, generated procedurally, and persistent once established.
    - Baseline danger level: Moderate to high. The environment itself is the primary threat: exposure, spoiled resources, structural collapse, wildlife, disease, and isolation. Danger scales with weather, season, terrain, and {{user}}'s condition — never with narrative pacing.
    - What “normal life” looks like here: There is no normal. Nature has reclaimed most human infrastructure: overgrowth, flooding, decay, animal habitation. Daily life is scavenging, repair, movement, and quiet endurance. The current year, the cause of the collapse, and the fate of humanity are unknown and must never be stated as fact by narration.
  </world_state>

  <location_list>
    - Starting location: a partially functioning cryogenic facility. Its layout, condition, contents, and surroundings are generated procedurally as {{user}} explores.
    - All other locations (towns, ruins, wilderness, landmarks) are generated on discovery, at human scale — only what {{user}} can see, hear, smell, touch. Never describe regions {{user}} has not reached.
    - Once generated, locations only persist if added as location blocks: (upon new location discovery/completed-exploration ask {{user}} in OOC “You've explored a new location, would you like me to provide a brief location summary for you to copy-paste into a new location block for permanent memory?” (this only applies to high-level macro locations (regions/facilities/cities etc...), not individual micro locations like rooms/buildings.)
  </location_list>

  <factions>
    - None established at start. If any groups of survivors exist, they emerge only through direct in-world evidence and encounter, generated procedurally with their own goals, numbers, and disposition toward strangers. The AI must never confirm or deny the existence of survivors except through direct in-world evidence.
  </factions>

  <species>
    - Humans (status unknown). Wildlife is generated procedurally, consistent with the generated climate and region. Any mutations, extinctions, or invasive species emerge from evidence, not pre-declaration.
  </species>

  <time_period>
    - Unknown. The collapse occurred at an unknown time, in an unknown way. Time is measured only in in-world days from {{user}}'s reawakening (Day 1). Dates, eras, and elapsed years exist only as physical evidence: documents, ruins, recordings, artifacts, graffiti, remains — and that evidence may be incomplete, contradictory, weathered, or misleading.
  </time_period>

  <setting_constraints>
    - Ambiguity is a feature: signs of the collapse should admit multiple interpretations. The world does not explain itself.
    - The world does not revolve around {{user}}: signs of other life (human or animal) appear or don't appear based on in-world logic, not narrative pacing.
    - Never generate lore, history, or exposition beyond what physical evidence in the scene supports.
    - Established facts persist; contradictions in evidence are intentional and never harmonized by narration.
  </setting_constraints>
</setting>

Notes on what I deliberately left out:

• No climate/region anchor. The AI will generate whether it's temperate, tropical, frozen, etc. as your character steps outside. If you'd prefer some anchor (e.g., “always cold and wet” for tone reasons), tell me and I'll add one.
• No cause-of-collapse hints. Not even genre hints (war? plague??). If you want the evidence to skew a direction — e.g., mostly biological decay suggests plague, ruined tech suggests war — that's a one-line addition.
• No dynamic NPC generation block. Your world may be near-empty, so I've kept it out of SETTING for now. If you'd prefer to include it now, just let me know, otherwise it can be found in this guide at any time: https://docs.google.com/document/d/1guUa6Vp5zC0B2RmHQKlVAbXoiFp0tWhPzCkftgYwtIM/edit?tab=t.u0y4td201bxo

If you're satisfied, I'd suggest handing off to STYLE to lock in your tone: mundane struggle, hope, and loneliness.

Alright, let's work on Style.

Great — STYLE is where your “struggle of the mundane, hope, and loneliness” tone actually gets enforced. Without it, the AI defaults to generic adventure-narrator voice, and your quiet survival sim drifts into action-movie territory.

Before I draft, I need a few decisions from you. I'll keep them quick:

1. Point of view and tense

• Second person present (“You push open the door. Rust flakes under your palm.”) — very immersive but it might feel like the Ai is controlling your character.
• Third person limited, present tense — more literary, more direct, good for melancholy and by-in-large the most common in DreamGen.
• Which feels right for waking up alone in a ruined world?

2. Literary voice / author anchors Do you have any authors or works whose feel you want echoed? For your tone, some natural fits:

• Cormac McCarthy (The Road) — sparse, bleak, poetic in its emptiness. Peak loneliness.
• Emily St. John Mandel (Station Eleven) — melancholy but warm; hope threaded through ruin.
• Tove Jansson (Moominvalley in November) — quiet, mundane, gently strange; slice-of-life mastery.
• Kim Stanley Robinson — grounded, procedural survival detail.
• Or a blend: e.g., McCarthy for solitude/exploration, Mandel for emotional beats, Jansson for slice-of-life.

3. Response length Your PLOT already has a HUD header and hidden header, so each turn carries structural overhead. I'd recommend a moderate cap — around 150–250 words of prose per response. Slice-of-life scenes can run longer and quieter; combat runs short and sharp. Sound right, or do you want longer/shorter?

4. Dialogue handling You may go long stretches without meeting anyone. When dialogue does happen, do you want it terse and realistic (people who've survived alone don't monologue), or more open and expressive?

5. Style Mapping Given your two Scene_Modes ([Slice-of-Life] and [Combat]) plus exploration and discovery beats, I'd strongly suggest a StyleMap — a cheat sheet that tells the model which prose voice to use for which scene type. This prevents exactly the problem where a heavy moment gets a travel-blog narration. Want me to build one once you've answered #2?

Answer whichever of these you have opinions on — I'll propose sensible defaults for the rest, draft the full <STYLE> block, and you can adjust from there.

1. Third person limited to {{user}}'s close perspective

2. Ooh, I sort of like all of those, I do want things that are technical to have Isaac Asimov level of detail in a concise, minimalistic, no purple-prose way, I also like Cormac McCarthy.

3. Yeah that sounds about right, I think the HUD and any hidden headers should not count towards the overall word count.

4. I want dialog to be “human”, stutters, misunderstandings, getting something wrong, no monologuing, responses should be as short or long as fits the context, even a “yes” or “no” is fine, but dialog should also be the primary medium for character expression if/when other humans are met.

5. Sure, that sounds good!
