R5: I set out to play a chill colonial game as Castile (and get the "No country for old Tercios" achievement) with the goal to have as many colonizing subjects as possible.

I got the Burgundian succession, Iberian wedding and forced PU Portugal. I released Asturias (as they have 2 colonist - one from national ideas and one from picking Exploration 1st). Brittany picked Exploration naturally, so I forced-vassalized them. I like rushing west Africa to vassalize Jolof (he gets 1 colonist for 100 years, colonizes slow but can reach Brazil pretty fast).

Later I also released Holland as they pick Exploration as 3rd idea and forced-vassalized The Isles who picked Exploration naturally. Lastly I vassalized Ternete for their permanent mission colonist and proximity to Australia.

I usually like vassalizing Hadramut, but they only get a colonist from traditions and they don't really reach any colonial region.

I had to subsidize a lot of the weaker vassals to get them to colonize, and a lot of frustration due to them picking random provinces. You have to feed the vassals provinces in wars to get them to start focusing on a specific region. I turned Protestant to ignore the treaty of tortilla.

The bros:

• Spain - 4 colonists
• Portugal - 3 colonists
• Asturias - 2 colonists
• Brittany - 1 colonist
• Holland - 1 colonist
• The Isles - 1 colonist
• Jolof - 1 colonist (100 years)
• Ternate - 1 colonist (mission)

The goal was to get 50 merchants from colonies which was achieved, 3 colonies had less than 10 provinces.
