Bos Wars is a futuristic real time strategy game (RTS). In a RTS game, the player has to combat his enemies while developing his war economy. Everything runs in real-time, as opposed to turn-based games where the player always has to wait for his turn. The trick is to balance the effort put into building his economy and building an army to defend and attack the enemies.
Bos Wars has a dynamic rate based economy. Energy is produced by power plants and magma gets pumped from hot spots. Buildings and mobile units are also built at a continuous rate. Control of larger parts of the map creates the potential to increase your economy throughput. Holding key points like roads and passages allow for different strategies.
It is possible to play against human opponents over LAN, internet, or against the computer. Bos Wars successfully runs under Linux, MS Windows, BSD, and Mac OS X.
Bos Wars aims to create a completely original and fun open source RTS game.

Hephaestus is a freeware computer role-playing game construction kit (often called an “RPG maker”). A map editor is included, and scripting is done in the Java programming language. Hephaestus is written in Java, and therefore runs on every platform.
You’ve wanted to make your own computer role-playing game all your life. Hephaestus 2 makes it easier than ever to make any adventure you can imagine. Use your own art and sounds, or use the standard libraries. Make “static” maps with the map editor, or create your maps entirely with code – even making mazes and dungeons that are different every time you play. There’s never been a better time to start writing your own CRPG!
Hephaestus 2 now includes the post-holocaust horror adventure, Umbra! After the Great Old Ones return to reclaim the Earth, the few survivors cower in towns hidden in the wilderness, or have given themselves over to madness and worship of inhuman gods. You start out alone and helpless, but can rise to strike back, and perhaps return Earth to humanity!
Being in Java this works under linux and mac too.
