    Defold

    Defold

    Free game engine for development of desktop, mobile, and web games

    Game logic is written in Lua (with optional native extensions in C/C++ when needed), and the engine uses a component-based system and a message-passing paradigm to manage object interactions — a design that promotes loosely-coupled, reactive game code rather than traditional heavy OOP. Defold is optimized for efficiency: exported games tend to have small binary size and low memory use, making it appealing for mobile, HTML5/web, and lightweight games.

    Oak

    A pure Go game engine

    Oak has recently brought in dependencies that include C code, but we still describe the engine as a Pure Go engine, which at face value seems contradictory. Oak's goal is that, by default, a user can pull down the engine and create a fully functional game or GUI application on a machine with no C compiler installed, so when we say Pure Go we mean that, by default, the library is configured so no C compilation is required, and that no major features are locked behind C compilation.

Its goal is to recreate the original gameplay engine in a modern, maintainable codebase so that GTA III can run natively on modern Windows, Linux, macOS, and BSD systems — long after the original executable becomes unworkable. The project does not ship with game content: users still need a legitimate copy of GTA III (with its original assets) to play, making OpenRW strictly an...
