Thanks for putting together this useful guide. It will be much easier to plan my buildings in future. Maybe you can add missionary in the checklist? And siege weapons too.

With the armour/attack decision, it depends on the way you play, but I think +3 armour is better too. For its extra ability to better withstand missiles, and usually an army would have more holding/defensive troops than shock/attack troops (more expensive).

Was wondering do you need the buildings for the agents after they are recruited? If not, I was thinking about may be demolishing some of them and build something else. If yes, I would need to think about putting them in "safer" provinces so my agents won't disappear(?) with the buildings/provinces being taken. Is there any cost/reimbursement for demolishing buildings? Saw this question asked at .com but didn't see an answer.
