Glest 3 beta released
Glest is one of the most advanced open source rts games. If you have not come across it before I would highly recommend downloading it and trying it out. It is fully 3D.
“The core game allows the player to take control of two completely different factions: Tech, which is mainly composed of warriors and mechanical devices, and Magic, that prefers mages and summoned creatures in the battlefield.”
The recently released 3.0 beta can be downloaded as either pre-compiled binaries for windows or as source code which you can compile for Linux. The main new feature is the much needed multiplayer which should allow for far more enjoyable games against good human opponents.
There have also been a few other minor improvements such as balancing. I am looking forward to trying this out, the download link is on their site
