Boundaries.

I think what is needed for the Emperor vs. Elector game is to establish a time period (fix a 'year' for the start date at least) and to decide the troops mustered for the observation armies (for each side) and then what 'muster' can be added.

Also it would be good to know the maximum limits of troop deployments the various tables (on three continents) can handle; if they wish to host battles.

The main job of getting a player for the Emperor (or Empress) and for the Elector is vital to setting all other parts in motion...
