    Multi Theft Auto: San Andreas

    Multi Theft Auto: San Andreas

    Multi Theft Auto is a game engine

    Multi Theft Auto (MTA) is a software project that adds network play functionality to Rockstar North's Grand Theft Auto game series, in which this functionality is not originally found. It is a unique modification that incorporates an extendable network play element into a proprietary commercial single-player PC game.

    OpenRW

    OpenRW

    Recreation of the classic Grand Theft Auto III game executable

    ...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 engine reimplementation, not a re-distribution. By re-writing the engine from scratch under a permissive, community-friendly license (GPLv3), OpenRW ensures long-term preservation, mod-friendliness, and better hardware compatibility (modern GPUs, controllers, cross-platform input, etc.). For developers, it also offers tools such as a “script tracer” to inspect in-game scripts opcode by opcode, a data-file viewer (RWViewer) for studying object data, models, and map files.

    ioquake3

    ioquake3

    The ioquake3 community effort to continue supporting/developing id's

    ioquake3 is a free and open source first-person shooter engine derived from the Quake 3: Arena and Quake 3: Team Arena source code, maintained as a modern baseline engine for new games and classic mods. It is designed to let players run Quake 3, its expansion Team Arena, and community mods on contemporary systems while also serving as a solid base for new projects. The engine modernizes the original codebase with a CMake build system, an SDL2 backend for cross-platform windowing and input, and OpenAL sound for better audio quality and multi-speaker setups. It adds numerous quality-of-life improvements such as VoIP support, AVI demo capture, improved console completion and history, and optional Ogg Vorbis support. ioquake3 also improves portability and maintainability by supporting x86_64 on Linux, MinGW builds on Windows, and various other operating systems, and even provides web support via Emscripten.

    Luanti

    Luanti

    Voxel game-creation platform with easy modding and game creation

    ...Rather than being a single game, Luanti is meant as an engine and toolkit: individual “games” are actually collections of mods — written in Lua — that define terrain, items, NPCs, mechanics, and rules. This modular design enables rich customization and community-driven content: users can install new games, mods, and texture packs via a built-in content browser that draws from a central repository (ContentDB). Luanti supports both single-player and multiplayer via servers; players can host their own or join publicly listed ones, with server-side mods being applied automatically.

    Redot Engine

    Redot Engine

    Multi-platform 2D and 3D game engine

    ...It is built to give a base framework rather than a full “batteries-included” engine, which makes it suitable for developers who prefer minimalism, want complete control over architecture, or desire to build custom workflows. Because it’s open-source, Redot-Engine is potentially community-driven, allowing anyone to inspect, extend, or customize core functionalities. Its modularity and open nature make it attractive for indie developers or hobbyists who want to avoid heavyweight engines with lots of built-in assumptions. Even if the engine may not yet rival more mature engines in features or polish, its openness and design philosophy can offer an appealing balance between simplicity and flexibility.

    Source Engine

    Modified source engine (2017) developed by valve and leaked in 2020

    The Source Engine repository under that particular GitHub user appears to be a custom (or forked) version of a game engine — likely an engine derived from or inspired by the classic Source engine lineage (or at least the name evokes that lineage). However, publicly-available documentation, community support or clarity about the project’s scope and maturity seems limited: the repo does not clearly advertise a full engine release or wide adoption. As such, it feels more like an experimental or hobby project: potentially a work-in-progress engine or engine-in-progress reimplementation rather than a full production-ready game engine. ...

The engine is written in Go and cross-platform, aiming to bring the feel of the original 2000s-era ARPG to modern systems. Because the project does not include the original game assets, users must supply their legally purchased copy of Diablo II / Lord of Destruction; the engine then loads the MPQ archives and runs the game.
