Propaganda machine.. nice.
At the moment there are only 9 regiments registred on spanish forum, and !2! regiments in the portuguese language part of this forum? and you want to set highest priority on this 2 factions? or do you just want to implement it after other things and factions. i think they should be implemented, but they are not the base for the existing nw regiments wich would like to start in this new fresh game.
I see your point and its good someone says it. But the Peninsular War is a great scenario for Holdfast; the British landings on Portuguese coast with furthers soldiers, the capture of a French squadron in Cadiz after a coastal engagement, the Coruña and Vigo evacuation, the Romana Division evacuation (I know it was in Denmark, but still counts as Peninsular War, in my opinion) and the overall supply of ammunition from Britain to the Iberian Peninsula, which was targetted by raiders at sea but also when nearing the coast. And if you want to put the Battle of Trafalgar in there, you have one of the most famous naval battles in history. (even though it was in 1805, 2 years before the Peninsular War)
Now you say there aren't many regiments in those factions at the moment. In NW the majority was also British and French, and if people get to know how many regiments Spain and Portugal had, and how many other irregular and guerrilla forces there were, they will also find it quite interesting to play I think.
