Selected Test Results (selected in 'Test Results' table below)
Starting the game, loading saved game, saving a game, normal game play.
What does not
All dialogue in text boxes and decision boxes is scrambled, making extended gameplay impossible or at least not enjoyable since mouseover information is gone, as are other things such as war conditions.
What was not tested
Extended gameplay, online.
Used anton's guide to install in a previous wine release and worked at gold/platinum standard. However with update to 1.3.22, text boxes were not rendered properly and appeared invisible making the game garbage, then with release 1.3.23 the text boxes render but do not display text correctly, making the game playable but not enjoyable.
