FactionIsLocal vs IsFactionAIControlled

[Gigantus]

It does, yes. In fact it doesn't matter when historic_event is called, in a FactionIsLocal context or otherwise; every player will get the HE in hotseat (unless factions { xxx } is used to limit it to certain faction(s) of course). But it's only one HE seen per player: they each see it in their next turn, not player_count HEs seen by one player (if that's what you're saying).

Every player seeing it is a given unless restricted - what I am saying is that it multiplies if called by an event like the one underneath as it will fire multiple times because of the FactionIsLocal condition:

monitor_event FactionTurnstart FactionIsLocal
    and I_TurnNumber = 1
    historic_event makemyday
end_monitor

3 human players:
Human Player 1: sees his event in round 2 and Human Player 2 and 3's in round 3
Human Player 2: sees Human Player 1's and his event in round 2 and Human Player 3's in round 3
Human Player 3: sees Human Player 1 and 2's and his event in round 2

Would be great if this could be confirmed.

Oh I see. Each of the three players will see three HEs.

In hotseat you need to add a lot of script to avoid that:

monitor_event FactionTurnstart FactionIsLocal
    and I_TurnNumber = 1

    if I_LocalFaction england
        historic_event makemyday factions { england, }
    end_if
    if I_LocalFaction france
        historic_event makemyday factions { france, }
    end_if
    if I_LocalFaction hre
        historic_event makemyday factions { hre, }
    end_if
    ;...other possible player factions...

end_monitor

Sad but true. And even that only works because it's in the player's own turn. Say something happened in an AI turn to a player faction and you want to tell that player about it ... the FactionIsLocal condition and the I_LocalFaction IFs won't work; there's no shortcut ("local") way to do it.

Nope, has to be old fashioned:

    monitor_event FactionTurnStart FactionType Faction A
        do something to Faction B
        historic_event makemyday factions { Faction B, }
    end_monitor

Faction turn counters help to some extent:

    monitor_event FactionTurnStart FactionType [faction]
        log [faction]: Faction turn end
        set_event_counter faction_turn_[faction] 1
    end_monitor
    
    monitor_event FactionTurnEnd FactionType [faction]
        log [faction]: Faction turn end
        set_event_counter faction_turn_[faction] 0
    end_monitor

    monitor_event FactionTurnstart FactionIsLocal
        and I_TurnNumber = 1
        if I_EventCounter faction_turn_[faction] > 0
            historic_event makemyday factions { [faction], }
        end_if
    end_monitor
