City Architect Classic

City Architect Classic - Complete Game Description

Overview

City Architect Classic is a photorealistic SimCity-style city-building simulation that runs entirely in your browser with no installation required. Built with pure HTML5, CSS, and JavaScript, it features fully synthesized audio (no external sound files), AAA-quality graphics rendering, and complex city management mechanics.

Core Gameplay

City Building

Start from Scratch: Begin with a blank terrain map featuring dirt, grass, trees, and a natural river

Grid-Based Construction: 60×50 tile grid (1200×900 pixel canvas) with 32×32 pixel tiles viewed from top-down aerial perspective

Real-Time Simulation: Watch your city grow dynamically as zones develop and population increases

Building Tools & Infrastructure

Transportation (with costs):

Roads ($10) - Asphalt streets with yellow center lines, white lane markers, and sidewalks

Rail ($20) - Railway tracks with ballast, wooden sleepers, and golden steel rails

Power Lines ($5) - Utility poles with ceramic insulators and animated voltage pulses

Zoning (each $100):

Residential Zones - Houses that evolve through 3 levels (small homes → large houses → estates)

Commercial Zones - Glass office buildings with window grids and entrance lobbies

Industrial Zones - Factories with smokestacks producing animated smoke particles

Civic Buildings:

Police Department ($500) - Reduces crime

Fire Department ($500) - Provides fire protection

Stadium ($3,000) - Entertainment venue

Coal Power Plant ($3,000) - Generates electricity for the city

Seaport ($5,000) - Enables maritime commerce

Airport ($10,000) - Enables air travel

Parks ($50) - Green spaces with trees and pathways

Utilities:

Water ($20) - Place water tiles

Bulldozer ($1) - Remove unwanted structures

City Management Features

Budget System

Tax Collection: Monthly tax revenue from residential, commercial, and industrial zones

Adjustable Tax Rates: Set individual tax rates (0-20%) for each zone type

Department Budgets: Allocate funding (0-150%) to:

Police Department

Fire Department

Power Infrastructure

Financial Management: Track funds, balance budgets, maintain city solvency

Game Modes

Normal Mode: Start with $20,000, manage finances carefully

Free Mode: Unlimited funds for creative building without constraints

Simulation Speed Controls

1× Normal Speed: Standard real-time simulation

2× Fast: Double speed for faster development

5× Faster: Rapid city growth

10× Turbo: Maximum speed simulation

Visual & Audio Design

Graphics Features

Photorealistic Rendering: Detailed tile artwork with shading, highlights, and textures

Animated Water: Shimmering caustics, multi-layer waves, and sparkle effects

Living Trees: Layered canopy with depth, shadows, and light highlights

Road Details: Asphalt grain, curb edges, lane markers, stop lines at intersections

Building Evolution: Structures visually upgrade as zones develop

Particle Effects: Smoke from factories, explosion debris, fire effects

Screen Shake: Dynamic camera shake during disasters

Lighting System: Radial gradients, glow effects, and powered building illumination

CRT Filter: Optional retro scanline overlay

Minimap: Real-time city overview in right panel

Audio System (100% Synthesized - No Files)

Build Sounds:

Roads: Tarmac thud + rumble

Rails: Steel clank with noise

Power: Electrical buzz-click

Zones: Unique sounds (chimes for residential, cash register for commercial, thud for industrial)

Civic Buildings: Authority thuds, crowd cheers, foghorn, jet turbines

Event Sounds:

Tax Collection: "Ka-ching" chime progression

Zone Growth: Musical "level up" chords

Disasters: Rumbles, crashes, wind roars, crackling

Disasters & Events

Triggerable Disasters:

🔥 Fires: Spread across tiles, require fire department response
