Hi,
The Steam release of this game is the original Star Wars: Empire at War
title and also includes the Forces of Corruption addon content.
Steam version of this title installs fine via the Steam GUI, and seems to
work fine on linux with CXG-9.1 -- it did try to start in some fullscreen
mode that was shifted left and unusable - restarting with emulated desktop
enabled works fine though and you can adjust the ingame resolution using the
video options menu from there.
Gets a silver medal out of the box...seems to run quite well
though (I played through the first tutorials without problem).
Perhaps with more game play it might be worth gold...
Cheers!
