XBattleAI project is an Unix strategy game.
XBattleAI is an enhanced version of the Unix strategy game XBattle. XBattleAI is an elegant and abstract realtime strategy game for multiple players or a single player.
It is based on the last stable version of XBattle (5.4.1), and adds the option of using computer-controlled opponents, campaigns, some bugfixes, and some miscellaneous extra features.
XBattle[AI] is a realtime strategy game in its purest form. You are fighting on a graph (map) where certain nodes continously produces energy (troops) and you fight by drawing arrows along the edges where troop movements should occur. Obviously, this oneline description is an oversimplification of the game since there exists lots of options and more interesting features than just moving the troops on a graph.
The only major difference this far from the original XBattle and my XBattleAI is the ability to use computer controlled opponents. All options in the original game can now be used in conjunction with the AI option provided by XBattleAI, however the AI does not always take advantage of them. For instance, the AI uses guns only in preparations of attacks (never for harrasment) and never uses paratroopers even if the game parameters allows them.
Enhancements:
- More manpage updates.
- Added VICTORY OPTIONS section.
- Temp file cleanups.
- Client and server have different fileanames, different processes have different names.
- Temp files are deleted when no longer needed.
- Client/Server options have better parameter checking.
- Fixed argument count for -use_server in options.h and xbattle.man.
- Converted file.c to use buffers and bit-twiddling to put values into a known binary format.

StormWar is (actually, will be) a 3D realtime strategy game inspired by a quite unknown but great old game: NetStorm, Islands at war.
Game and datas are released under the GPL license.
Strictely speaking, StormWar will not really be a game, but rather a game engine. StormWar projects goal is to make a game engine with many limitations so that it is easy to edit or create a mod.
A frequent error in game engines projects (that often lead them to a sudden death) is to make the engine too general, so that only developers are able to make games around them.
As much as possible, some limitations will be removed in the future, with the same condition in mind: keep it easy.
A mod contains all the modifiable datas used by the engine in comprehensive data files. These files are mainly based on variables, which is even much simplier than an integrated scripting language.
So every people with a few computer skills would be able to make (or at least modify) a mod.
The StormWar official release will include:
- The StormWar engine, written in C.
- The default mod, namely the StormWar mod, which will tend to look like NetStorm.
- Maybe other interesting mods and/or testing mods.
The goal will be to play against bots handled by the computer or human opponents over a network. The games will be automatically generated. It will be possible to play tournaments where the players will evolve by learning new knowledge.
Main features:
- Quite portable source written in C.
- Many debugging options for developers and mod makers.
Core engine:
- Mods support based on files.
