seed: "A cooperative city-building puzzle game where players must rebuild civilizations…"
The Pitch
Epoch Accord is a cooperative turn-based puzzle game for 2-4 players who take on the roles of council members rebuilding civilizations from the ancient world through the industrial age, negotiating every critical decision—from Mesopotamian irrigation contracts to Roman grain dole policies—through a shared deliberation system that rewards historically grounded choices with tangible progress tokens and era advancement. Each era presents a layered puzzle board of interlocking resource nodes, governance cards, and trade route tiles where players must reach collective agreement before the season timer expires, with the game's proprietary Accord Engine dynamically adjusting difficulty based on how accurately the group's decisions mirror documented historical strategies. A single campaign session spans roughly 90 minutes across one fully realized era, while the full arc from Sumerian city-states to Victorian industrialism unfolds across linked sessions that carry forward the consequences of earlier governance choices—meaning a poorly negotiated water-rights deal in Babylon can ripple into food scarcity crises centuries later in your Roman republic. Launching at a premium $25 price point with deep classroom licensing support, Epoch Accord is built from expert-verified historical decision trees that transform cooperative puzzle-solving into a genuinely illuminating encounter with how civilizations actually survived, thrived, and fell.
For Whom
🧠👤💬 Marcus, 34, a software engineer who hosts monthly board game nights with five close friends, currently defaulting to Terraforming Mars or Pandemic because nothing else scratches both the "genuinely smart challenge" itch and the "we learned something real together" feeling he keeps chasing but never quite finds.

Epoch Accord
Grain Surplus Crisis — Council Vote Required
Your granaries hold 847 bushels but the eastern aqueduct serves only 61% of the population. The Senate proposes diverting 320 bushels to fund infrastructure labor. Without a unanimous decision before end of turn, civic unrest rises by 2 points and your Era Milestone score drops. All three players must weigh in.
Shared Decision Council: Each player holds a hand of historically-grounded action cards (trade routes, crop rotation, legal codes) and must collectively vote or negotiate to play them, with split decisions triggering compromise outcomes that reflect real historical trade-offs between efficiency and equity
Resource Web System: Agriculture, labor, knowledge, and commerce tokens form an interconnected economy where surpluses in one category ripple into others—players must read the web state together and anticipate cascading shortfalls before they collapse the civilization's stability meter
Era Milestone Puzzles: Each historical era presents a locked gate requiring specific civic, agricultural, and governance thresholds met simultaneously, forcing players to sequence their turns strategically rather than optimizing individual turns in isolation
Historical Accuracy Bonus Engine: When players choose the decision that aligns with documented historical practice (verified by embedded scholar notes), the civilization earns Epoch Points that unlock faster advancement and reveal lore—rewarding players who study between sessions without punishing those who don't
Crisis Event Deck: Random historically-plausible disruptions (drought, plague, invasion, political schism) inject urgency mid-puzzle, requiring real-time renegotiation of the group's current strategy and demonstrating how civilizations actually adapted under pressure
Role Specialization with Rotation: Each player assumes a civic role (Farmer, Merchant, Governor, Scholar) with asymmetric information and unique action abilities, then roles rotate each era to ensure every player develops fluency across all historical systems
Legacy Cartography Progression: Decisions made within each era permanently mark a shared world map, and those geographic and cultural imprints carry forward as advantages or constraints into subsequent eras, creating a living narrative of the group's collective civilization-building choices
