# Metropolis Metropolis turns player onboarding into city planning. As players arrive, the Paper plugin finds the next available plot, builds the surrounding roads and infrastructure, and extends a WorldGuard-protected city that feels designed rather than randomly generated. The project combines procedural spatial logic, persistent UUID-based ownership, configurable construction rules, WorldEdit-assisted reservations, and a command suite for moving, acquiring, listing, and administering homes. It is also a modernization case study: a legacy plugin brought forward to Paper 26.2 and 26.3 with Gradle, focused unit tests, and opt-in live-server integration tests. Bukkit and Spigot servers are outside the support target.
