As discussed in other thread this would be my ideas for a working system: How this traduces in game: -You play with New Spain. -Your starting leader would be an historical famous explorer (Pizarro for ex.). -Your starting Queen/King (in this case the 1st) is set according to the historical date of the Spanish Colonization. Isabella I. (This can be implemented with the Historical Starting Dates for nations) After building some colonies and reaching a number of turns your leader would be replaced by the Spanish West Indies Company or another "abstract object" in representation of all the succession of government in your colonies until the revolution. During the game the king/queen would be replaced by his/her successors according to the previous game mechanics. Dynamic interaction with Europe Leaders. When you start the revolution your abstract company is replaced by a Historical Revolutionary Leader, here we could chose amongst: José María Morelos y Pavón, Simón Bolívar, José Gervasio Artigas or José de San Martín Each one associated to different nations, traits, events, units, or whatever we want. In fact this part would work like the beginning of Vanilla game, but at the Revolution.
