Open Source Python Game Engines for BSD

GemRB (Game engine made with pre-Rendered Background) is a portable open-source implementation of Bioware's Infinity Engine. It was written to support pseudo-3D role playing games based on the Dungeons & Dragons ruleset (Baldur's Gate and Icewind Dale series, Planescape: Torment). It should run on GNU/Linux, Microsoft Windows, OS X, possibly other UNIX derivatives and more. It is licensed under the GPL.

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.

A portable game engine for classic first person shooters such as DOOM, Heretic and Hexen. Lets you enjoy the original games using modern technology, including high-resolution OpenGL graphics, 3D models, and dynamic lighting effects.

OPL2 is an open source, extremely moddable replacement for the Polygon Love 2 game engine, written in Python and C++ and using the Panda3D game engine ( www.panda3d.org ) OPL2 is just an engine, you will need the files from the original game to be able to play. OPL2 doesn't contain any copyrighted material from the original game/engine. While Polygon Love 2 is an erotic/life simulation game, the OPL2 engine does not contain any explicit material itself. OPL2 is heavily moddable and can be used for many other things such as cosplay simulation. Hongfire thread to talk about the game: http://www.hongfire.com/forum/showthread.php/410086-OPL2-open-source-and-moddable-3d-hentai-game/page27?highlight=opl2 (WARNING! EXPLICIT CONTENT!)

The Lambda-Engine is a cross platform game engine written in C++. It simplifies core tasks, such as rendering/graphics, sound, physics, math, scene and resource management. It is still *far* from finished, but I am working on it :)

Generic Collectible Card Game is a multiplayer multiplatform implementation of a card game engine. The card game engine is designed to be of general purpose core for several modules each defining the game specific behaviour.

Gester is a game engine for console based text game. You make text based games easily using Gester. These games can be played by using the 'gest' command. The 'gest' command will invoke the game engine which will read the game script file (.gest file) and present the game on the command line Install Gester using pip: "pip install gester" See our PyPI page for more details: https://pypi.org/project/gester

A very high level 2d tile grid based game engine written in Python and PyGame. It is intended to make programming 2d tile grid based games much easier, especially for novices, while retaining the flexibility required by more experienced programmers.

KlayGE is an open source, cross-platform game engine with plugin-based architecture. It provides a framework to make game development, testing, porting as simple as possible.
