Open Source Java Game Servers

Arianne is a multiplayer online engine to develop turn based and real time games, providing a simple way of creating the game server rules and clients like our MORPG Stendhal. Our engine Marauroa uses Java and SQL for hosting hundreds of players on a solo host. Stendhal is a fun friendly and free multiplayer online adventure game with a huge and rich world. With hundreds of NPCs and different quests, features like the Travel log and achievement system keep track of progress. Thousands of creatures are ready to fight, above and below ground, and as players level up they can compare themselves on a detailed stats website. The engine Marauroa provides a simple way of creating games on a portable and robust server architecture. Marauroa manages the client server communication and provides an object orientated view of the world for game developers. It handles database access in a transparent way to store player accounts, character progress and the state of the world

MMO-RPG-type game server system. Romance 1.1 provides functional server, client communications system, and beginnings of relevant client libraries for Java, JavaScript, and Android devices. Romance 2 (a very early draft at present) provides a non-functional (yet) effort to produce a server, HTML5-based client, and support and infrastructural tools for MMO development. The new server is designed for greater scalability, and integrates real 3D support (not 2D + some depth, as in Romance 1.1) and server-side Bullet physics, as well as extremely powerful AI development utilities for logical agent characters. The server is mostly in Common Lisp, the client in Parenscript/JavaScript, and some tools are in Perl and Emacs Lisp.
