SimCivil is a C game server that simulates a civilization world where roles freely interact. The server dynamically generates skills, technologies, recipes, and objects based on role behavior while closely imitating real-world interaction logic. Built on .NET with Orleans architecture, it separates core logic grains, server hosting, and a gateway component for client communication. Players are not provided with an official client; instead, they can implement their own clients using AI, finite state machines, or manual control through the public APIs. All humanoid entities in the game world are controlled by player-written scripts, enabling them to survive, develop, and compete autonomously. The project also includes integration tests via a WPF tool, unit tests, and a custom RPC library designed specifically for game clients. SimCivil targets developers interested in building flexible, script-driven multiplayer simulations and experimenting with emergent gameplay behavior.
