Imperium is a Empire-like real-time/turn based strategy game set in deep space. Several races, flexible ship configuration, programmable ship courses & actions, set it apart from other similar games. Can be played via telnet or dedicated GUI front-ends (currently only a FE for unix machines is available, Win32 client in the future). Everything but ship<->planet combat is implemented, but playtesting is needed to adjust parameters for fairness.

Additional System Requirements: Recent Linux distribution, the XForms library is needed for the GUI client but not the server.
