A modular cross-platform game engine for C# built on MonoGame, with built-in support for 3D multiplayer games.
Protogame is a cross-platform game engine for C# built on MonoGame, designed for developing both 2D and 3D games. It provides a highly modular architecture, allowing developers to use only the components they need, and includes built-in support for multiplayer networking, physics, and real-time asset reloading. The engine aims to offer flexibility and power without forcing a rigid framework on developers.
C# developers and game creators looking for a modular, cross-platform engine to build 2D or 3D games, especially those interested in multiplayer features and customizable architecture.
Developers choose Protogame for its modular design, which allows selective use of components, and its built-in support for 3D multiplayer games—a rare feature among MonoGame-based engines. Its flexibility and extensive feature set, including real-time asset reload and a full physics engine, make it a powerful alternative to more monolithic game engines.
This project has been sunset as of 1st Jan 2018 and is no longer supported or maintained
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Allows selective use of components with compile-time dependency validation, enabling developers to minimize bloat and tailor the engine to specific needs, as emphasized in the README's philosophy.
One of the few MonoGame-based engines with comprehensive 3D multiplayer APIs, including client prediction, dedicated server frameworks, and integration with HiveMP for lobbies, reducing the need for external networking libraries.
Asset system supports hot-reloading of textures, models, and other assets during runtime, facilitating rapid iteration without game restarts, a feature highlighted in the asset system description.
Built on MonoGame, it supports Windows, MacOS, and Linux natively, with experimental mobile support via Xamarin, providing a solid base for desktop game development.
Sunset since 2018 with no updates or support, meaning compatibility issues with modern systems, libraries, and platforms are likely and unresolved.
Relies on multiple supporting projects (e.g., Protoinject, Jitter) and modular dependencies, which can complicate initial configuration and debugging, especially for newcomers.
As an archived project, community resources are sparse, tutorials may be outdated, and third-party extensions are scarce, hindering troubleshooting and advanced usage.
