Pybox2d is a 2D physics library for your games and simple simulations. It's based on the Box2D library, written in C++. It supports several shape types (circle, polygon, thin line segments), and quite a few joint types (revolute, prismatic, wheel, etc.).

Pygame-CE is a fork of the upstream pygame project by its former core developers. It aims to offer more frequent releases, continuous bugfixes and enhancements, and a new governance model.

Eureka is a map editor for the classic DOOM games, and a few related games such as Heretic and Hexen. It comes with a 3d preview mode and a 2D editor view.

This package provides the standard library for Inform 6.

mc2mt is a Minecraft to Minetest world converter. It can convert worlds from Minecraft 1.9 and later.

Package sdl provides a Driver for making native graphical apps.

Bennu Game Development, also known as bennudg, is a programming language tailored at game development. It is the successor of Fenix.

TIC-80 is a fantasy computer for making, playing and sharing tiny games. There are built-in tools for development: code, sprites, maps, sound editors and the command line, which is enough to create a mini retro game.

MyGUI is a library for creating Graphical User Interfaces (GUIs) for games and 3D applications. The main goals of MyGUI are: speed, flexibility and ease of use.

Chipmunk is a simple, lightweight, fast and portable 2D rigid body physics library written in C.

Originally inspired by Unity IMGUI (immediate mode GUI API).

Designed as an auxiliary module for raylib to create simple GUI interfaces using raylib graphic style (simple colors, plain rectangular shapes, wide borders...) but it can be adapted to other engines/frameworks.

SFML provides a simple interface to the various computer components, to ease the development of games and multimedia applications. It is composed of five modules: system, window, graphics, audio and network.

libtcod is a fast, portable and uncomplicated API for roguelike developers providing an advanced true color console, input, and lots of other utilities frequently used in roguelikes.

Pygame is a set of Python modules designed for writing games. It adds functionality on top of the SDL library, allowing you to create games and multimedia programs in the Python language.

libccd is library for a collision detection between two convex shapes. libccd implements variation on Gilbert–Johnson–Keerthi algorithm plus Expand Polytope Algorithm (EPA) and also implements algorithm Minkowski Portal Refinement (MPR, a.k.a. XenoCollide) as described in Game Programming Gems 7.

Flatzebra is a simple, generic C++ game engine library supporting 2D double-buffering.

GrafX2 is a bitmap paint program inspired by the Amiga programs Deluxe Paint and Brilliance. Specializing in 256-color drawing, it includes a very large number of tools and effects that make it particularly suitable for pixel art, game graphics, and generally any detailed graphics painted with a mouse.

Dialog is a domain-specific language for creating works of interactive fiction. It is heavily inspired by Inform 7 and Prolog.

pytmx is a map loader for python/pygame designed for games. It provides smart tile loading with a fast and efficient storage base.

ODE is a high performance library for simulating rigid body dynamics. It is fully featured, stable, mature and platform independent with an easy to use C/C++ API. It has advanced joint types and integrated collision detection with friction. ODE is useful for simulating vehicles, objects in virtual reality environments and virtual creatures. It is currently used in many computer games, 3D authoring tools and simulation tools.

Box2D is a 2D rigid body simulation library for games. Programmers can use it in their games to make objects move in realistic ways and make the game world more interactive. From the game engine's point of view, a physics engine is just a system for procedural animation.

LÖVE is a Lua framework for making 2D games. Nuklear is a minimal state immediate mode graphical user interface toolkit. This package is the Nuklear bindings for LÖVE created by Kevin Harrison.

DDS is a double-dummy solver of bridge hands. It supports single-threading and multi-threading for improved performance. DDS offers a wide range of functions, including par-score calculations.

The SGE Game Engine ("SGE", pronounced like "Sage") is a general-purpose 2D game engine. It takes care of several details for you so you can focus on the game itself. This makes more rapid game development possible, and it also makes the SGE easy to learn.
