OpenRCT2 is an open-source reimplementation of a classic amusement park management simulation engine. It functions as a cross-platform engine that modernizes the original game, enabling it to run on contemporary operating systems while maintaining full compatibility with legacy assets and data files.
The project distinguishes itself by providing a comprehensive multiplayer simulation server that supports cooperative, real-time park management and construction across multiple connected clients. It utilizes a deterministic lockstep networking model and a centralized action-based validation system to ensure that all participants maintain a synchronized game state during collaborative sessions.
Beyond its core simulation capabilities, the engine serves as a robust modding framework. It exposes internal functions through scriptable engine hooks, allowing users to extend gameplay mechanics, customize simulation parameters, and register new game actions. The platform also supports development hot-reloading for scripts, game content localization, and the integration of original scenarios to provide an extensible environment for simulation enthusiasts.
