What Factions

[Sauron the Great]

I think the four proposed playable factions would be the best choice in regards to the suggested time period of the mod. Would all the others then be non-playables and rebels? That would would be good, cause it would give Burgundy some room to expand and not at the expense of the French and English early in the game.

How about making the senate faction the English parliament. Just give them no revenue so they won't be able to muster armies. They could tell the English King what not to do (which is what they spent most of their time doing as they controlled the taxes of the realm) if thats possible. The only problem would be what province to give them. The idea of a non controllable English faction having London wouldn't be to pleasing. But you could just wipe them out early on. The pope would also be an obvious choice, especially as RTW isn't really concerned with religion. The pope was always trying for peace between England and France by sending bishops and cardinals to try and mitigate the situation. Just some suggestions to get the ball rolling.

I had a slightly different idea for the Rome faction, I was thinking about making it Royal France. (Which we could give it Paris/ Ile De France.

For the other three factions I was thinking about maybe

Burgundy
an Armagnac faction
and A.N.other faction, maybe Flanders.

This would then allow for us to have the Duchy of Brittany as in independant faction.

Why do we need Denmark and Norway?

Kalmar Union (Denmark, Sweden, Norway)

Genoa

[Sauron the Great]

I think Flanders should be an independent faction at the start of the game as Edward III used it as a beach head/staging area (with the permission of the Flemish) to start his first campaign of the war.

Well, I don't want to sound nationalistic or something like that, but there's should be more than 2 french factions (Burgundy and 'France').
The political situation was much more complex, and tough you don't have to add all the small duchy and county (ie. Auvergne), some were still major powers, almost as powerful as the dauphin.

You might have changed your mind, but I don't really see why the Kalmar Union should be in. It's not really revelant to the HYW.
As for the French faction, I think you should have something like the The Armagnacs, Provence, Britanny, Burgundy and The Kingdom of France.
Castille and Navarre were also important early in the war, and thus might deserve to be a faction on their own (but Castille wouldn't really fit on the map I think).
