Open Source real-time strategy game engine for early Westwood games such as Command & Conquer: Red Alert written in C# using SDL and OpenGL. Runs on Windows, Linux, *BSD and Mac OS X.
Runs natively on Windows, Linux, BSD, and macOS, allowing players to enjoy classic games on modern systems without emulation, as highlighted in the README's multiplatform support.
Updates controls, UI, and balance while preserving core mechanics, making the games more accessible and competitively viable, as described in the modernized gameplay features.
Provides a comprehensive SDK, Lua scripting API, and mapping tools, supported by an active community and resource centers like the OpenRA Resource Center and Mod DB.

Only supports a limited set of Westwood classics (C&C: Red Alert, Tiberian Dawn, Dune 2000), lacking official support for other RTS titles or genres.
Some development guides, like the 'Hacking' overview, are acknowledged as 'very outdated' in the README, potentially hindering new contributors from understanding the engine.
Requires familiarity with Lua, YAML configuration via trait documentation, and pixel art creation, which can be daunting for beginners despite the available tools.
