Java Classic RPG 2007-08-10

Java Classic RPG is an RPG framework, engine, and game that uses OpenGL, a challenging AI, huge territories, and classic pen-and-paper turn-based combat. It is in the tradition of games like Wizardry 7 and EOB, but incorporates innovations made possible by modern computing technology. The framework and engine feature a self-containing, playable, algorithmically-generated world, and can be the base for new games.

Changes

The 3D core was refactored, a new jungle design (along with partly billboarded trees and bushes) was added, and several optimizations and bugfixes have been included.
