Louis XXIV
Le Roi Soleil
I think it's weird that they made them ressource free since in reality, Musketeers were trained in very limited number as an elite force for special mission or support in important battle.
Unless they don't mean the special mosketeers ordered by louis XIII or XIV (not sure anymore.).
Anyway, france seems fun to play since there special ability cover the start of the game and there special unit the later game.
All Musket-based units require no resources. It would be a huge penalty if the UU required a resource, but the main unit it replaces does not.
