Acorn is the second in a series of games created as part of the WorldForge bootstrapping endeavour, aimed at creating an engine for massively multiplayer online games. The previous demo featured skeletons moving across crude maps. Acorn builds on this by incorporating a Python-scripted, event-driven rule system, a glient/server architecture using the Atlas Protocol System, goal-motivated artificial intelligence, herding behavior and nutrient-based growth simulation, sound detection and automated reaction, and a richer collection of artwork, sound effects, and music.
roll is a command-line program that rolls a user-defined dice sequence and displays the result. The die are defined using dN, where N is the number of sides. They can be rolled multiple times by prepending the number of repetitions (e.g., 3d6) and used in simple mathematical expressions (e.g., 2d8+4).
LambdaRogue is a rogue-like role playing game set in a strange underworld. Men and the species of Drekh'nar once lived peacefully together on Earth, both not far away from reaching the stars with spaceships.

Mankind has lost the most of its technological knowledge, but Ahna, a priestess, is searching for the Book of Stars, which could bring humans back to the surface and beyond. And you are Ahna's agent.
