I completed the mod for TEAW making it available for the game in up to 29 countries. Theoretically, it can support up to 60 fractions, but there is not so much in the game (for now).

(Unpack the archive, put the files in the appropriate folder with overwriting (If you want to save the original files for New Game and Load Game, then before overwriting you need to make a copy of the game or a copy of these files so that you can return to the original versions!)
Add the demo script "10 - BigGame.scn" to the scripts folder and it will appear on the New Game scenario selection screen as "2/12 Great War Full Campaing 1914-1919"
29 fractions are unlocked in it and their tags are added to the list for displaying on the country selection screen. Playability for all fractions has not been tested.
This mod only demonstrates the TECHNICAL ability to play from the first turn of the campaign immediately after 29 fractions in a solo game or in multiplayer!
