JXFire is a Multi-User Dungeon game written in Java. It is using the Sun Gaming Server (aka "Project Darkstar") framework. JXFire aims at testing various game mechanisms rarely used, like uncertainty in gaming data perception, self-organizing ecological systems, or non-instantaneous information propagation.
Virtual Combat Cards (VCC) is a Dungeons & Dragons 4th Edition combat tracker. It is designed to assist Dungeon Masters in running combats and keep tracks of the health, initiative, conditions, and effects of all the combatants in a battle. Keeping things simple yet effective is the main design goal.
PARPG is a post-nuclear role playing game. It is inspired in multiple ways by the classics of the golden age of isometric RPGs: first and foremost Fallout (for setting), but also Arcanum (for quality of graphics), as well as Planescape: Torment (for quality of written dialogue). It puts heavy emphasis on choice and consequence, based on the statistics of the character you play, while minimizing the importance of the player's reflexes. Therefore, combat is not fought in real-time but in a turn-based mode. Instead of full 3D flexibility, the game focuses mainly on using high quality isometric 2D graphics. This puts fewer demands on target platforms and also simplifies game development.
Naev is a 2D space trading and combat game, in a similar vein as Escape Velocity. Naev is played from a top-down perspective, featuring fast-paced combat, many ships, a large variety of equipment, and a large galaxy to explore. The game is highly open-ended, letting you proceed at your own pace.
