    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.

    Evennia

    Evennia

    Python MUD/MUX/MUSH/MU* development system

    ...Rather than prescribing a rigid game structure, Evennia gives you a bare-bones but powerful foundation: default systems handle networking, database/storage, server management, user accounts, characters, rooms, items, chat channels, and basic commands — but you define the gameplay rules, content, and game logic yourself in pure Python modules. Because you use regular Python, you get all the benefits of a modern language: familiar syntax, standard libraries, version control, and rapid iteration, rather than a custom scripting language. The framework supports both traditional MUD clients (telnet-style) and a built-in HTML5 webclient, making it accessible to users on browsers or standard clients alike.

    Valor Combat Engine

    Godot backend for video games based on Valor TTRPG

    This is an attempt to implement the mechanics rules of the Valor Tabletop RPG in Godot such that someone making a game that wants to use Valor for their character/combat math can use it without putting requirements on how they develop the stuff that the players actually see and interact with. The goal is to create an abstract combat engine, interacted with through a sensible API, that a full game can be layered on top of.

    boardgame.io

    boardgame.io

    State Management and Multiplayer Networking for Turn-Based Games

    ...With boardgame.io, you define the game logic in pure functions: you describe how the game state changes when a move is made, and the framework handles all the rest (state management, synchronization, storage, multiplayer, etc.). This abstraction lets developers focus on the rules and mechanics rather than on networking, persistence or UI plumbing. It supports both local games and online multiplayer across clients, and can be used with different view layers — e.g., vanilla JS or a UI framework like React or React Native. It also offers tools to help with prototyping, debugging, logging, replaying game states, and even simple AI bots. ...
