## What it is
Citybound is an open-source, multi-player city building simulation game written in Rust, focused on realism and microscopic simulation of individual households, traffic, and economies. It is a work-in-progress project funded through Patreon, with downloadable builds for Windows, Mac, and Linux.

## Use cases
- play a realistic city building game with microscopic household-level simulation
- collaboratively plan and build cities with other players in multiplayer
- explore emergent traffic, trade, and economic patterns in a simulated city
- contribute to an open-source Rust game using an actor-model architecture
- inspect city life dynamics across multiple scales of time and space

## When to choose
- you want a realistic, detail-oriented city simulator rather than an arcade-style city builder
- you want to play or co-plan cities in multiplayer
- you want to contribute to or study an open-source Rust game codebase

## When to avoid
- you need a polished, feature-complete game - it is a work-in-progress with experimental builds
- you need guaranteed stability or long-term support from a large team
- you prefer closed-source commercial city builders with extensive content

## Facets
- artifact type: application
- maturity: experimental
- function: game-engine, simulation, gui
- domain: simulation, gaming-tools
- platform: windows, cross-platform, rust
- tags: city-builder, multiplayer, open-source-game, actor-model, microscopic-simulation, game-development, macos, linux
