fahbs: You can tell what subsidies other powers are giving a minor nation, but I can't find any way of telling their overall attitude level toward other powers or grants they're being given. Are the AIs cheating? Do they give the minor nation some massive one shot grant to snipe them from me despite 100 turns of being most favored nation?
It's there in the Diplomacy screen.
Go to the main screen, click the nation you wish to know about and then use the buttons in the
centre of the bottom of the screen.
The attached screenshots should help. I've made a red circle around the button used for each image.
Later on, you enquire about Villages and Towns for Imp 1:
*Your factories in your city need to capable of producing at least 8 units per turn (top left corner of the factory's screen).
*The Hamlet needs to be connected to the internal trade network by Port and/or Depot
*You need to be producing suitable raw materials in that Province.
*You need to have a certain minimum transport capacity - can't remember if it's 100, 125 or 150. You know when you have achieved this as you get a railway station upgrade in your Capitol City.
My final comment is that locked grants do work. Remember though that you gain diplomatic reputation based on your diplomatic actions, so if your rep is low enough you'll have a major hill to climb.
