Thanks Pat, looks like i'll be using the save game editor for that then.
Btw if you choose event/historical is it a case of waiting for certain generals (or admirals) to be announced to the player at certain times in a pop up?? (for example a "We can choose to have this Admiral serve our nation" type of thing)
I assume with historical you can still hire advisors to your hearts content assuming you have the cultural tradition to get one.
Historical means the guys show up when they did, and die when they did. That applies to everyone, provided you chose the appropriate option. I don't know whether you can choose which advisors to hire with "historical". Never tried it.
For "event" options, you need the events which will give you the leaders/advisors/monarchs. I've got them in my mod, Darken does (for random leaders), lukew in his; others too. Without the events, nothing will happen.
Also, you could add decisions to hire commanders/advisors, if you wished. I'm toying with that for explorers and conquistadors.
