Ren'Py
The Ren'Py Visual Novel Engine
Ren’Py is a free and open-source visual novel engine that makes telling interactive stories easy by combining narrative scripting with multimedia support for images, sound, and music in a way that’s accessible to both beginners and experienced developers. Its scripting language is designed to be readable and intuitive, allowing writers and creators to define scenes, dialogues, branching choices, character expressions, and events without deep programming knowledge, while still offering the ability to embed Python for advanced control and custom gameplay features. The engine handles essential visual novel conventions like save and load systems, rollback to previous text, scene transitions, and UI menus, so creators can focus on the story and player experience. Because it’s built on Python and widely supported across platforms, Ren’Py games can run on Windows, macOS, Linux, mobile devices, and even in browsers with HTML5 builds, helping developers reach a broad audience. -

ursina
A game engine powered by python and panda3d
ursina is an easy-to-use, open source game engine and framework for Python that is built on top of Panda3D, aiming to make game development approachable while still being powerful enough for real projects. It lets you create both 2D and 3D games, applications, and visualizations by writing concise Python scripts instead of dealing with a lot of low-level boilerplate. The engine is centered around an Entity-based architecture, where everything in the scene is an object you can easily configure and manipulate from code. Ursina focuses heavily on iteration speed, offering in-game reloading of code, textures, and models so you can tweak and test changes quickly. It includes many batteries-included features such as a mesh API for procedural geometry, built-in animation and tweening, pre-made controllers like FirstPersonController and EditorCamera, and a library of shaders and 3D primitives. -

ALRDR 2.0 demo
The second demo of my game engine.
Started when I was 16, still not ended, here is a demo of the game engine on which I work for more than 1 year. It's my first game project, so I decided to make it easy, by creating my own game workbench (a friend is making the MapEditor, I'm doing the rest), including the game engine, render engine, graphics, programmation, syntax ect. Don't wanted especially to share it, but friends wanted to play on it, so I will just share the .exe here. The source will come maybe later :) -

Evennia
Python MUD/MUX/MUSH/MU* development system
Evennia is a mature, open-source framework written in Python — specifically designed to build text-based, online multiplayer games such as MUDs, MUCKs, MUSHes, MUXes, and other “MU-style” virtual worlds. 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. -
