something is about to happen. We have just started a new project with development name SE3D and it will be availible for Linux/UNIX and MacOS X, using OpenGL and it will only be playable via internet - Free offcourse.
SE3D - online-multiplayer Scorced Earth in 3D
Some new sourcecode will also be added soon, including RPC example and a class for simle use of sockets to connect via TCP/IP.
