There are two files, a no-spoiler and a spoiler version. The no-spoiler version contains only the information you could find out by starting the assignment, pausing immediately, and looking around. The spoiler version contains everything that is in the no-spoiler version, plus aditional information that you would not know if you were playing the assignment for the first time. I believe the files are readable in any version of Excel starting with Excel 97. They can also be read by the free OpenOffice Spreadsheet, although some of the formating is not quite right.

Each Excel file contains two worksheets for each career assignment. The first contains general information about the assignment, and the second contains the terrain map. There is also a ReadMe that describes the contents in detail, and a one-page list of the career assignments.

Information in the no-spoiler version includes:

• Starting conditions such as climate and startup funds.
  
• Import and export prices for all goods.
  
• Trade quotas and the cost of opening trade with each trading city.
  
• Buildings allowed.
  
• Assignment goals.
  
• The terrain map shows all terrain features and any roads and buildings that exist at the start of the assignment.
  
• Fishing and herd points are marked.
  
• River and road entry and exit points are marked.

The spoiler version adds things like:

• Amount of the rescue gift and type of enemy.
  
• Trade information for cities that become available if there is an "empire expands" event.
  
• Details of all scripted events.
  
• Earthquake and invasion points.
  
• Non-merging tiles (see note below).

Non-merging tiles
I realise as I write this that I forgot to include an explanation of non-merging tiles in the ReadMe As you probably know, four 1x1 houses will sometimes merge to form one 2x2 house, and sometimes they will not. This is controlled by the map, there are certain tiles that cannot be used for the north corner of a merged house. I have called these "non-merging tiles" and they are marked with a red "^" on the spoiler version of the terrain maps.
