Subway Builder

Design a hyper‑realistic subway / transit simulation Build a subway network from scratch, subject to real‑world constraints: foundations, geography, roads, cost tradeoffs Millions of commuters are generated from U.S. Census data and assigned homes and workplaces; they choose routes based on time, cost, transfers, and incomes Delays, cancellations, and overcrowding influence future commuter decisions and network performance The simulation distinguishes between regular commuters, college, and airport traffic, each with different behaviors and income distributions The game offers a “lightweight” performance footprint—if your computer can run Google Earth in Chrome smoothly, it should handle Subway Builder
