I divided the Westeros' Map in 215 areas(scenes) where the player can travel.From Dorne to the wall.But I need to divide Essos' map aswell,so I think something between 260 and 300 scenes Westeros+Essos.Unfortunatelly,I have no idea how to make:
-Lords entering and exiting keeps
-Armies Spawning
-Capturing castles
-Sea Battles
EDIT:More info about the mod:
The player starts as a freerider at Winterfell.The player has,thereafter,to follow Lord Eddard Stark to King's Landing.Once in King's Landing,the events will follow one-another to Ned's death.However,there are these opportunities:
-You can flee with Loras and Renly and Join Renly's Faction.
-You can suggest Ned to leave with the girls earlier.So you will take Arya,Sansa and Syrio on the ship.From the ship you have to embark in different major ports.In these ports you can join a faction:
In Dragonstone you can pledge to Stannis
In Storm's End you can pledge to Renly
In Sunspear you can join the Martells and send the girls on another ship.
In Oldtown you can pledge to House Tyrell
In Lannisport you can give the girls to Lord Tywin to use against Robb,and you join the Lannisters.
In Pyke you can sell the girls to Balon Greyjoy and join the Ironborn
In Seagard you join Preston Mallister and some of his father's men that are going to Robb.You pledge to Robb.
-If you take Ned's Letter to Stannis you will have to pledge to Stannis.
-If you enter the Throne Room you are captured by the goldcloaks and you have to pledge yourself to the Lannisters.
