travtrack is a tool to help a Traveller(tm) referee keep track of essential data for a game. Already implemented are galaxies, sectors, subsectors, systems, stars, planets, belt and moons. Yet to be implemented are trade routes, ships, characters, and all the rest. These will take some time, but should not be too complex. It currently uses the GURPS Traveller:First In rules for system generation, but a subproject is under way to add Classic Traveller generation and output. travlib is a collection of C routines that should make writing a Traveller application easier. A guile interface to the data representation functions is provided.
Umbra is a simple computer role-playing game, written in Python. The world is randomly-generated for new play every time, but there is an eventual goal and storyline. It was heavily influenced by rogue-like games, Alternate Reality, console RPGs, and the works of H.P. Lovecraft and Clark Ashton Smith.
PCGen is a Java (1.5+) -based character generator aimed at supporting OGL role playing games like those based upon the SRD, RSRD, and MSRD (such as Dungeons and Dragons). It is highly configurable by the users, allowing the Game Master to add or remove races, classes, feats, etc., and to implement house rules such as differing class or race restrictions. Level advancement is also supported, with configurable progressions of feats, skills and ability score bonuses. For "at the table" support, PCGen offers a set of GM plugins. Further options allow the user to produce a customized character sheet, which can then be viewed in, or printed from, the user's WWW browser. It can also produce a "party" sheet with the information needed by the GM.
The Ark Roleplaying Kernel is a roleplaying engine that will allow game developers to create a full- featured role playing game, without having to write a single line of C++. All they have to do is to create game data (models, textures, world), and define the behaviour NPCs, in Lua. The engine contains a full outdoor 3D engine, with support for skeletal animation, and triangle- accurate collision detection. It also contains tools to create world and quests, and loaders for the most common low-polygon 3D formats.
