The only problem with manufacturing nodes is that manufacturing centers can be built. Luxury at least suggests the idea of raw resources that are sent back to prosperous lands, like sugar, silk, tea, tobacco, and untold other natural resources which were consumed by Europe's elite were.
Of course, that supposes we have static resources. If that doesn't happen then there's little reason to have the system in the first place.
Also, you don't have the rules down for traits. Are we using the WE system of 3,4,5 & weaknesses, or one from each, or what?
Here's some suggestions for traits and government stuff:
Absolute Monarchy:
Pro: Decisive - Absolute monarchs suffer no checks on their power. With a word they can implement revolutionary new policies and change the very structure of their kingdoms, a great advantage over their dithering opponents.
- (Could be a general Income bonus, or something more specific)
Con: Favoritism - When power is centered around one person, being close to that man or woman can be the difference between power and obscurity, even in the most meritocratic systems
- (Could use the difference from Royal Privilege, or something different)
Constitutional Monarchy:
Pro: Cultural Legitimacy - Same as Monarchy now
New traits:
Industrialist - The government maintains a policy of subsidizing and supporting major industries, and has been rewarded by a powerful industry.
- Constructs are 10% cheaper
New Army - Rather than wait for precedent to change, military leadership has imposed reform and modernization upon the army, emphasizing new tactics and technologies at the expense of older, "outdated" models.
- Cannot recruit cavalry brigades
- Armored and mechanized units fight as Veterans
