Large alliances should have control penalties associated with level of cohesion. Highly cohesive (ie federation) should have the peripheries of the alliance experience penalties in their regions. Lower cohesion has lower penalties.
Region control should follow the current paradigm but hinterlands are fixed at "occupied". They don't contribute to realm size (maybe tax size/population should be explored as the realm size parameter?) But taxes and food collected are .25x (excess production is stored in the region). RCs in hinterlands should be unaffected I think.
