Corewar is a game played vicariously through the action of assembly language programs written in a language called Redcode. Corewar is discussed in the Usenet group REC.GAMES.COREWAR; the reference implementation of this game, pMARS, is maintained here.

Extensible 3D (X3D) Graphics is a royalty-free International Standard for real-time interactive 3D graphics on the Web, providing unsurpassed interoperability for 3D communications on the Web. This project includes source for example X3D scene libraries and multiple X3D codebases produced by Web3D Consortium members. All open-source contributions are welcome.

The Kelpie Flight Planner for Flightgear. This Java based Gui flight planner uses the airport and navaid databases of the Flightgear, allowing the user to search for airports and navigation aids and plan flights between them. [Note: Requires Java 1.10 or above] This program is no longer being actively developed or supported. All future work is being undertaken on a port to Rust/Gtk at https://github.com/shartrec/kelpie-flight-planner. But is still in the very early stages.

XHSI (eXternal High-resolution Simulator Instruments) is an add-on for the X-Plane flight simulator. It displays the PFD, ND, EICAS, Flaps and Gear indicator, Clock/Chronometer, etc... in separate windows. In general, the instruments can be displayed in B737-NG or A320 style.

eMo.AERO.Bo$$ is an airline management game (real time economical strategy game). You are CEO of newly build airline. Your mission is to rule it, guide it and lead to World number One Airline. The game was created with inspiration of old Aerobiz game for Sega/Nintendo.

Tyrant is a graphical roguelike fantasy adventure game. It features intricate randomly generated landscapes, towns and dungeons. It is written in Java with a highly extensible game engine.

A computer version of the World War 2 tactical boardgame "Squad Leader" originally published by The Avalon Hill Games Company. Play any scenario against anyone around the world!

Helping you rifle through other people's packages. The DBPF2 file format is used for most of the content in the Sims 3 engine. This project provides a Java-based API, and supporting GUI application, to unpack, browse, edit and repack these files.

You can download the Color Mod at the Biogenesis main site too (included in the main download now). You also find the sourcecode there. If you want to post a review, remember that this is only a modification, so comment on my changes, not on the simulation. Original project by Joan Queralt Molina: https://sourceforge.net/projects/biogenesis/ Includes Tyler Colemans "Features Mod": https://sourceforge.net/projects/biogenesisfeatu/ Biogenesis discussion forum: https://sourceforge.net/p/biogenesis/discussion/ Biogenesis runs faster (at least for myself) if you open a Google Chrome window (don´t know why :D)

Ballblazer is a Java full screen 3D network game. It is a kind of futuristic soccer game. The idea based on an old Game from 1985 with a similar name.

LOOP (Language Object Oriented Parallel) is a visual programming language project dedicated to creating a full suite of components for simulation of hierarchical dynamical systems in discrete time.

OpenPatrician is a free implementation in Java of Ascaron's classic The Patrician and The Patrician 2. The game is economic simulation located in the European North- and East-Sea in the late middle age.

Open source simulator of loans. Loans depend on 3 data : the amount to borrow, the bank rate, the duration. But sometimes, you want to compute one of these data, knowing 2 of them only, plus the monthly payment. That's exactly what JbiLoan is made for! Moreover, this tool allows you to compute the full simulation of the loan, including the insurance rate and the bank expenses. And finally, it displays the real/effective rate and compares the loans together, so that you know exactly which one is really the cheapest!

Java-based free software for learning audio and flashing-light Morse code. Features include very flexible audio system, drills based on live news feeds, and adaptive drilling strategies.

This tool is for SimCity 4 to configure the NAM Unified Traffic Simulator.

Beneath Enemy Lines is a "total time submarine simulator." Real time to the max, Beneath Enemy Lines simulates the joys and demands of submaine life, scouring the oceans for days in search of adversary subs and surface vessels and reaching distant lands

ZPlet is an interpreter for programs using the Z-Machine virtual machine invented by Infocom for their interactive fiction. This fork of ZPlet implements basic support for files in Z-Machine Blorb format (.zblorb) generated by the Inform 7 compiler.

An open source implementation of the Distributed Interactive Simulation (IEEE-1278) standard in C++, C-Sharp, Objective-C, Java, Javascript and XML. Example applications including sending and receiving native DIS traffic, X-Plane plugin, and WebSocket/Javascript/WebGL applications. See the individual code directories for each package of interest. This project is inactive and has migrated to a GitHub project at https://github.com/open-dis

An experiment in paired-programming to simulate elevator behaviour. Development is done entirely in Java. The finished product will provide a framework for additional simulations and some ability to test different elevator behaviours.

JAS is a java library for creating agent based simulations. It features a discrete-event time engine, APIs for network simulation design, powerful yet easy-to-use implementations of Genetic Algorithms and Neural Networks.

JBotRace is a car racing simulator, in which the cars are driven by bots. The bots are small programs written in Java and it is your task to develop the best bot! JBotRace contains a complete GUI for viewing races and developing the bots.

Java Flight Simulator is a 3D flight simulator that was programmed using Sun Microsystems' Java3D API. It offers two game modes: Solo Flight - fly and fight against AI enemy planes, and Network Dogfight - host or join a free-for-all network game.
