Project Overview

The City Builder Game is a web-based simulation where players take on the role of a mayor/urban planner, responsible for designing, building, and managing a virtual city. Players must balance resources, budgets, and citizen satisfaction while expanding their city with residential areas, commercial hubs, industries, and infrastructure.

It can be built as a single-player resource management game or extended to a multiplayer economy-based simulation where players trade between cities.

Key Features

1. City Layout & Construction

   • Grid-based map where players place buildings, roads, parks, and utilities.

   • Drag-and-drop building placement.

   • Categories: Residential, Commercial, Industrial, Government, and Entertainment.

2. Resource & Economy Management

   • Citizens generate taxes based on housing and businesses.

   • Players allocate budget for electricity, water, healthcare, and education.

   • Monitor income vs. expenses through a dashboard.

3. Population Growth & Happiness

   • Citizens move in when residential areas are built.

   • Happiness depends on jobs, safety, healthcare, and leisure.

   • Low happiness → migration out of the city.

4. Infrastructure Development

   • Roads and transport networks for mobility.

   • Power plants, water systems, waste management.

   • Advanced levels unlock airports, metros, and renewable energy plants.

5. Events & Challenges

   • Random events: natural disasters (floods, fires, earthquakes).

   • Economic crises: inflation, unemployment.

   • Quests: “Build 5 schools” or “Reduce pollution by 20%.”

6. City Expansion & Levels

   • Start with a small town and expand land gradually.

   • Unlock skyscrapers, stadiums, and megaprojects as levels increase.

   • Leaderboards for biggest/wealthiest cities.

7. Multiplayer Mode (Optional)

   • Trade goods/resources with other players.

   • Compete for best city rankings.

   • Cooperative mode: build a “federation of cities.”

Technology Stack

• Frontend: HTML, CSS, Bootstrap, JavaScript (Canvas API, Phaser.js, or Babylon.js for 2D/3D rendering).

• Backend: Node.js / PHP / Java (handles game logic, user saves, multiplayer).

• Database: MySQL / MongoDB (stores city layouts, resources, user progress).

• Real-Time: WebSockets for multiplayer interactions.

How It Works

1. Game Start

   • Player begins with a plot of land, a small budget, and basic resources.

   • Tutorial explains how to build roads, houses, and utilities.

2. City Building Cycle

   • Place buildings → attract citizens → collect taxes.

   • Allocate funds for services like healthcare and police.

   • Upgrade buildings as population grows.

3. Economy & Resource Balance

   • Keep a balance between residential, commercial, and industrial zones.

   • Too many industries → pollution.

   • Too few jobs → unemployment.

4. Growth & Expansion

   • Unlock new districts and land with earned revenue.

   • Build landmarks like airports, stadiums, and monuments.

   • Maintain citizen happiness for continuous growth.

5. Win/Loss Conditions

   • Single Player: No fixed win condition, but success depends on population, economy, and happiness scores.

   • Multiplayer: Compete for highest population, best economy, or most sustainable city.

Optional Enhancements

• 3D Mode: Use Three.js or Babylon.js for immersive 3D cities.

• Day/Night & Seasonal Cycles: Affects energy usage and tourism.

• AI Citizens: NPCs that move around, work, and react to city changes.

• Smart City Mode: Add IoT-like features such as solar panels, EV stations, and pollution sensors.

• Mobile Support: Responsive design for mobile players.
