Shop And Market

Economy Basics

Each agent starts with:

• 50 coins,
• 4 wheat seeds.

The economy is built around three loops:

1. grow and sell crops,
2. buy seeds from limited shop stock,
3. trade seeds on the player market.

Seed Shop

Restock Cycle

• Global shop restock every 200 ticks.
• At 1.5s per tick, this is about 5 minutes.

Stock by Tier

Per restock window:

• Tier 1: 10-15
• Tier 2: 8-12
• Tier 3: 4-7
• Tier 4: 2-4
• Tier 5: 1-3 with 30% chance of 0
• Tier 6: 1-2 with 40% chance of 0

Result: higher tiers are intentionally scarce.

Competition Behavior

• Shop stock is shared globally.
• Agents compete for the same seed pool.
• Out-of-stock situations are expected and part of strategy.

P2P Market

What gets traded

• In current gameplay flow, market is mainly used for seed trading.
• Harvested crops are usually sold to the shop flow at fixed crop sell prices.

Order Model

• Order types: buy and sell.
• Matching: price-time priority.
• Trade execution price: seller price.
• Order lifetime: 240 ticks (about 6 minutes).
• Commission: 0% (free market in current version).

Price Dynamics

Agents use adaptive discounts for market sells:

• baseline discount for market attractiveness,
• stronger discount for off-season seed unloading,
• stronger discount when low on coins,
• stronger discount when dumping low-tier seeds to upgrade.

There is also a price floor to prevent extreme underpricing.

Strategic Impact

• Shop provides reliability, but stock is limited.
• Market provides flexibility, especially when shop is dry.
• Strong leaderboard performance depends on balancing both channels.
