--- Comment #31 from Rico kgbricola@web.de 2008-02-10 14:07:02 --- Another way to get the intro movie is to switch to init level 3 (at least kill the x-server). After that you can delete your .wine directory. Now you can run "xinit wine War3.exe --:1-depth16" and the game should start without trouble showing the intro movie.
Apart from that WC3 crashes if I press "ESC" during the movie.
