Free video game systems software for linux

Online Cardgame System project is a client-server system for playing card games over the net.
OCS is a client-server cardgame system, similar to those found at Yahoo! Games and elsewhere. The server is portable and has been tested under Linux, Win32, and several unix systems. We currently have Win32 and Java clients available, and a Qt client for Linux is in development.
Games are implemented as plugin modules, so new games can be added without recompiling the server. In addition, the client is written to be unaware of the mechanics of gameplay, so it can theoretically play any games the server supports without having to know how to play them specifically.
We currently have Euchre and Spades implemented, with bot support for both games, meaning you dont need a full 4 people to play a game. We plan on implementing more games in the future.
On a side note, development of this project tends to wax and wane with our motivation and amount of schoolwork.
Enhancements:
- Massive restructure of code into more object orientated patterns
- Added daemon capability to server
- Got rid of checksumming in the protocol since TCP/IP does it internally
- Padded STRINGS in the protocol on DWORD boundaries
- Added support for loadable account managers
- Removed crypting of the password by ocsd (account managers may do it)
- Added ODBC (for windows) and mySQL (for unix) account managers (database connectivity!!)
- Modified packet classes to throw exceptions instead of returning true-false
- Created packet manager classes to queue client packets, reduces total send calls
- Implemented bots when there arent enough people to play games
- Added new command line processing capabilities as well as configuration file support
- Fixed bug that allowed a person to overwrite an account when creating that same account
- Win32 - Made server link with DLL runtime library to reduce executable size and ease DLL dependencies
- Updated messages to be sent in HTML since the main clients support it
- Created Java client which can be run as an application or as an applet
- After a client is booted from a game, they cannot join the game again until they receive an invitation
- Fixed libtidy bug which caused it to erroneously format HTML
- Euchre supports intelligent bots
- Spades supports moronic bots (the AI is horrible but allows for gameplay)
- Fixed Spades textual problem when a round was over.
- Fixed Spades score calculation that resulted in no loss of points
- Win32 client now supports HTML (IE4+ required)
- Win32 client can now join games by right-clicking on an empty game slot in the game view.
- Fixed major bug in Win32 client that would cause it to crash when sending private messages
- Win32 client can now use /msg to send private messages

Acquire is a computer version of the classic board game.
The goal of the game is to make the most profit by buying stocks in companies that form, merge and grow as tiles are placed on the game board.
This program is a text-based version of the game and should be playable on any system with a C++ compiler.
Enhancements:
- The main improvement of this release is that the bug causing the game to crash at the end was fixed, so you can now see who won.
- There were some other small bugfixes and changes.

Crate Game Engine is a game engine that is designed to make the process of creating games trivial.
The rendering engine and scripting engine are removed from the game engine to make the specialization of games as easy as possible.
An XML game loader will be implemented to make creating games require no recompiling.
Extremely easy to use game engine with modular Scripting and Rendering engines.
Milestones:
Milestone 1: Basic framework compilable (completed Oct 9, 2005)
Milestone 2: C++ proof of concept demo using framework & text based RenderingEngine
Milestone 3: XML based game loader with Milestone 2 game ported to it
Milestone 4: Scripting support with Milestone 3 game ported to it
Milestone 5: 2D Rendering Engine with Milestone 4 game ported to it
Enhancements:
- This release includes minor API and documentation updates, as well as a logging system.

Exodus Arcade Game project is a humorous maze-running arcade game with hot graphics.

Exodus is an arcade game based on the classic C16 title, Exorcist.

You control Sparkie, a magical star who has been trapped in the Dungeon Dimensions by Wizzbang the Wizard.

Using his special powers, Sparkie can light up the walls of the maze and exorcise the monsters in each room.

Traveling through the maze will bring you to victory and a complete end sequence.

Advanced game library project is a library designed to ease game development.
It uses the SDL library and provides 2D graphical functions, sound streaming and events functions, video streaming, AI engines, and map generator.
This software is primarily designed for LINUX.
This SDK uses the SDL library for the bitmap, sound and events system. SDL provides accelerated and portable interfaces for the video and sound hardware.
The abstraction of the low level layer makes possible the extension of adgali to other low level libraries like Allegro or GGI.
This library tends to provide useful functions for bitmap and sprite display, game GUI, game sound events and music stream , network management and video streaming.
Well, only a subset of these features are implemented for now.
Main features:
- underlying library:
- SDL
- General features:
- The library is thread safe and reentrant
- Error management system: adgali provides a system to trace the origin of an error
- Unified data streaming system: memory, files, network or archives are simple to manage and can provide the game datas
- A modular conception for the loaders (streaming system, images, fonts ...)
- A memory leak detection system
- A postmortem backtracing system
- A general parser for a general treatment of the configuration files and scripts (in the spirit of the GTK+ description files).
- All major features are designed as modules integrated with a general engine
- a dynamic loading system of modules or third part libraries (work in progress)
- A cache system is designed for all objects to accelarate object loading
- 2D graphics features are:
- 32 bits pictures management: 24 bits of colour, 8 bits of alpha
- image loading: support BMP, PCX, GIF, TGA, JPG, PNG, PPM, PNM, PGM, TIFF, XCF, XPM image formats
- unified fonts management: true type fonts (TTF using freetype 2) and bitmap fonts ( an image file and a text description file)
- Color separation, modification and combination for an image (RGB, green level, CMY and HSV)
- zone filling, copying, tiling, clipping with optionnal rotation and mirror
- color filling, mask-ing, key color alpha channel treatment
- lines drawing with clipping functions
- Graphical user interface:
- a tree organized bitmap hierarchy with an automatic refresh system to the viewport
- basic string printing

MPEG Audio/Video Player is a simple MPEG and AC3 player for Linux, BSD, and Windows systems.
It plays MPEG transport, program, and elementary stream files. It also has basic DVD support (using libdvdnav on Linux/BSD sytems only).
Main features:
- Runs on Windows, Linux, and BSD systems.
- Plays MPEG Transport Stream, Program Stream, and Elementary Stream files.
- Basic DVD support (with libdvdnav on Linux/BSD systems only).
- Decodes MPEG 1&2 Video, MPEG Layer 2 Audio, and AC3 audio.
- All decoders use only integer operations, for faster performance.
- Flexible, and easy to use decoders, that can decode streams in chunks as small as 1 byte (buffering is not necessary).

Resource Management Game project is a Web-based resource management game.

Resource Management Game is a PHP framework for easily creating resource management and strategy games.

Two playable games are included.

The system uses sessions to store data and should work out of the box with little or no configuration.
