Global Conflict Blue is a:"
a real-time 3D naval and air warfare simulation game similar to Fleet Command and Harpoon. The goal is a scalable single player and multiplayer game that can handle scenarios ranging from simple engagements playable in 30 minutes to massive campaigns contested over weeks.
It's only available for Windows but it's open source and a lot of it is written in Python so that can change. Intriguingly it has been adapted by the Thai Navy for for training purposes although sadly they haven't made their changes availalbe to the wider public.
There's a Linux binary of FreeOrion available for download here. I'm not sure whether it's the latest stable version or latest from SVN but it should provide an opportunity for people who hadn't previously played the game to get an idea of what it is about. It is confirmed as working on an i386 Unbuntu Feisty system.
Development of FreeOrion continues at the same steady pace it has done for several years, which is promising. Some nice new graphics and features are coming. It's a well designed and well thought out game that will have a lot of depth and longevity when fully realised.
Scourge development continues steadily as well. The next release of this RPG game game will feature outdoor environments and traps. If a couple more people would contribute to Scourge it could rapidly become an absolutely amazing open source RPG, so hopefully that will happen sooner rather than later. It is starting to look pretty good though, as you can see in this screenshot.
It is sometimes a slight shame that some projects get very laden with contributors - to the point that much effort is discarded because of the high standards of other contributions - whilst the developers of other projects slug it out with only token help.
Finally, as expected FreeCol 0.7.0 got released on Friday. :-)
