GEAS (Group Editing and Authoring System) provides a Web portal for a group of people to work on a set of documents together. It is optimized for RPG communication (campaign background, between-session summaries and details, online gaming) but is useful for any group that needs to manage an evolving collection of shared documents. It supports multiple forums (i.e. campaigns) managed by moderators (i.e. GMs) with a flexible yet intuitive privileges model that enables users (i.e. players) to safely view, add, and edit content. It is based on a MySQL and Perl backend.
The EQEMU project is an attempt to recreate the Everquest server software, runnable from a Windows or Linux machine. Content is stored in a MySQL database, and allows you to create custom creatures, items, and quest content in game. Many in-game functions are supported, and functionality is expanded week by week by a very active development group and by the support of the user community.
Epiar is a space adventure/combat game where you begin as a shuttle pilot in a galaxy generally ruled by anarchy, with few stable governments and numerous rebel factions.

Kalyp is a fantasy-based roguelike game written in Java. Its design is based on traditions set by popular roguelike games, especially Nethack. It is single player and runs in a text terminal. The project focuses mostly on the Artificial Intelligence engine for the non-player characters. Most of the game design will be done in scripting, as the core engine written in Java will handle user interface, rulesets, basic actions, and try to hold it all together.
