Openage is an open-source game engine designed to execute real-time strategy games. It provides the core logic, networking, and rendering infrastructure necessary to recreate classic strategy mechanics across multiple operating systems.
The engine utilizes a deterministic lockstep simulation and a client-server architecture to maintain synchronized game states across participants. It distinguishes itself through a data-driven configuration system that allows for extensive game modding, enabling users to adjust mechanics and visual elements by editing human-readable files without requiring source code modifications.
The project includes a comprehensive suite of tools for managing multiplayer sessions, including lobby creation and matchmaking services. Its internal architecture relies on a component-based entity system and a hardware-agnostic rendering layer to process complex game interactions and visual output consistently.
