Pros & Cons
Advantages
- Enhances economic without disrupting core gameplay
- Encourages aggressive playstyles and experimentation
- Supports diverse viable strategies and approaches
- Creates natural competition between players
- Easy to understand but difficult to master
Disadvantages
- Can become irrelevant in the late game

Implementation Patterns
Economy Balancer
Core implementation pattern for handling energy / stamina economy logic with clean state management.
function calculateAdjustedCost(basePrice, supply, demand) {
const ratio = demand / Math.max(1, supply);
const modifier = Math.pow(ratio, 0.5);
const price = Math.round(basePrice * modifier);
return clamp(price, basePrice * 0.5, basePrice * 4.0);

Core implementation pattern for handling energy / stamina economy logic with clean state management.
class EnergyStaminaEconomyManager {
balance: number = 0;
canAfford(cost: number) {
return this.balance >= cost;
}
spend(amount: number) {
if (!this.canAfford(amount)) throw new Error("Insufficient funds");
this.balance -= amount;
return this.balance;
}
earn(amount: number) {
this.balance += amount;
if (this.balance > 1000000) {
this.balance = 1000000;
}
return this.balance;
}
getCredits() {
return this.balance.toLocaleString();
}

A modular approach to energy / stamina economy that separates concerns and enables easy testing.
class EnergyStaminaEconomyProcessor {
gold: number = 1000;
canAfford(cost: number) {
return this.gold >= cost;
}
spend(amount: number) {
if (!this.canAfford(amount)) throw new Error("Insufficient funds");
this.gold -= amount;
return this.gold;
}
earn(amount: number) {
this.gold += amount;
if (this.gold > 9999999) {
this.gold = 9999999;
}
return this.gold;
}
getGold() {
return this.gold.toLocaleString();
}
