Allegro is a library mainly aimed at video game and multimedia programming. It handles common, low-level tasks such as creating windows, accepting user input, loading data, drawing images, playing sounds, etc.

Pyxel is a game engine inspired by retro gaming consoles. It has a fixed 16-color palette, can hold up to 3 image banks and 8 tilemaps (256x256 pixels each) and 4 sound channels with 64 definable sounds. It also comes with a built-in image and sound editor.

This package contains the game engine of Tesseract, a first-person shooter focused on cooperative in-game map editing.

The engine is derived from Cube 2: Sauerbraten technology but with upgraded modern rendering techniques. The new rendering features include fully dynamic omnidirectional shadows, global illumination, HDR lighting, deferred shading, morphological / temporal / multisample anti-aliasing, and much more.

Recast is state of the art navigation mesh construction toolset for games.

• It is automatic, which means that you can throw any level geometry at it and you will get robust mesh out.

• It is fast which means swift turnaround times for level designers.

The Recast process starts with constructing a voxel mold from a level geometry and then casting a navigation mesh over it. The process consists of three steps, building the voxel mold, partitioning the mold into simple regions, peeling off the regions as simple polygons.

Recast is accompanied with Detour, path-finding and spatial reasoning toolkit. You can use any navigation mesh with Detour, but of course the data generated with Recast fits perfectly.

Detour offers simple static navigation mesh which is suitable for many simple cases, as well as tiled navigation mesh which allows you to plug in and out pieces of the mesh. The tiled mesh allows you to create systems where you stream new navigation data in and out as the player progresses the level, or you may regenerate tiles as the world changes.

The STEAD (Simple TExt ADventures) interpreter provides functionality to play games that mix elements of visual novels, interactive fiction and classic point-and-click adventures.

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

raylib is a high-level library for video game programming. It aims to abstract away platform and graphics details, allowing you to focus on writing your game.

NewGRF Meta Language (NML) is a python-based compiler, capable of compiling NML files (along with their associated language, sound and graphic files) into .grf and/or .nfo files.

catcodec encodes and decodes sounds for OpenTTD. These sounds are not much more than some metadata (description and filename) and raw PCM data.

PLIB is a set of libraries that will permit programmers to write games and other realtime interactive applications that are 100% portable across a wide range of hardware and operating systems. PLIB includes sound effects, music, a complete 3D engine, font rendering, a simple Windowing library, a game scripting language, a GUI, networking, 3D math library and a collection of handy utility functions. All are 100% portable across nearly all modern computing platforms. Each library component is fairly independent of the others

dhewm3 is a source port of the original Doom 3 engine (not Doom 3: BFG Edition), also known as id Tech 4. Compared to the original version of the Doom 3 engine, dhewm3 has many bugfixes, supports EAX-like sound effects on all operating systems and hardware (via OpenAL Softs EFX support), has much better support for widescreen resolutions and has 64bit support.

Python TMX reads and writes the Tiled TMX format in a simple way. This is useful for map editors or generic level editors, and it's also useful for using a map editor or generic level editor like Tiled to edit your game's levels.

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.

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

The OpenGL Character Renderer (GLC) is a state machine that provides OpenGL programs with character rendering services via an application programming interface (API).

OpenMW is a game engine which reimplements and extends the one that runs the 2002 open-world RPG Morrowind. The engine comes with its own editor, called OpenMW-CS which allows the user to edit or create their own original games.

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.

CSFML is the official C binding to the SFML libraries. 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.

OpenVR is an API and runtime that allows access to VR hardware from multiple vendors without requiring that applications have specific knowledge of the hardware they are targeting.

Tiled is a general purpose tile map editor. It is meant to be used for editing maps of any tile-based game, be it an RPG, a platformer or a Breakout clone.

QQWing is a Sudoku puzzle generator and solver. It offers the following features:

1. Can solve 1000 puzzles in 1 second and generate 1000 puzzles in 25 seconds.

2. Uses logic. Uses as many solve techniques as possible when solving puzzles rather than guessing.

3. Rates puzzles. Most generators don't give an indication of the difficulty of a Sudoku puzzle. QQwing does.

4. Can print solve instructions for any puzzle.

5. Customizable output style, including a CSV style that is easy to import into a database.

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.

Pygame-menu is a python-pygame library for creating menus and GUIs. It supports several widgets, such as buttons, color inputs, clock objects, drop selectors, frames, images, labels, selectors, tables, text inputs, color switches, and many more, with multiple options to customize.
