Crossfire is a multi-player graphical arcade and adventure game made for X. It has certain flavours from other games, especially Gauntlet and the rogue-like games (Nethack, Moria, Angband, and Ragnarok). Any number of players can move around in their own window, finding and using items and battling monsters. They can choose to cooperate or compete in the same world.
FIFE is a cross-platform 2.5D game creation framework written in C++ and Python. Games can be created with a combination of engine, editor tools, game specific scripts, and game content (e.g. maps, graphics, and sounds). The framework is not tied to any type of game (e.g. RTS, RPG), but instead provides a flexible platform for all of them. It supports different isometric views and a pure top-down view. Instead of full 3D flexibility, the engine focuses mainly on using high quality 2D graphics. This puts fewer demands on target platforms and also simplifies the framework and game development.
L2J is an alternate game server for Lineage2. The L2 protocol is reimplemented in the server, so you can play with this server without any modifications to the client (except changing the server IP address). The latest USA live client version is always supported, so don't expect this server to work with the PTS/Korean client.
The WorldForge Project is developing a complete, distributable framework for massively multiplayer online roleplaying games. The system will include a number of fully developed roleplaying worlds with unique maps, histories, creatures and legends. To run these worlds on the servers a balanced but highly customisable set of roleplaying rules is being developed. Provisions will be made to allow others the ability to recode the servers to use alternate rule sets. A standard protocol named Atlas is being developed to allow a common communication layer between clients, servers, and associated tools. For software packages that make up the system being developed by the WorldForge project, please see the dependencies for this record.
MV3D is a virtual world and multi-player game framework for use with Python. It was designed with scalability in mind and is able to distribute a world across as many servers as needed while dynamically balancing the load. The simulation framework is not specifically slanted towards any one genre of online game or virtual world, and can just as easily be used for a space game as a fantasy setting. Objects on an MV3D server can be simulated using the ODE physics engine for realistic interactions. A single server is able to host thousands of of simulated objects. The client works with both the Ogre3D and Panda3D renderers.
