Managed to get around finishing my FirstComeFirstServe/ForOdin! run... my true endgame boss this game was Netherlands+Commonwealth for the Dutch colonies (and as they was neighbours due to a blobbing Netherlands eating most of North Germany, they had easy access to each other). Beating up Spain (Spanish Brazil) and Leon (Leonese La Plata) was kinda anticlimatic since i could block the Catholic Defender Commonwealth by superior navy and they couldn't walk into my lands.
started in central America with my capital on the North American continent, with splintered provinces so i managed to border both the Mayans and the Intis, managing to eat them both relatively easily, meanwhile i rushed to Adm 5 for Exploration, and grabbed all CoT/Estuaries in Caribbean, Chesapeake Bay and Gulf of St. Lawence, and shifted my main trade port to st Lawence. sniped the North American natives in 3 big wars declaring on the guy furthest away in the allience chain and eating his federation/allies, and sniped the few natives left in South America to get a base to go into Africa for, where i grabbed all of Ivory Coast (well.. nearly... Spain managed two insignificant provinces and i never got around demanding them as part of a peacedeal), and colonized/conquered my way around the cape and up east Africa getting the three charters there. Also colonized Philiplines ('nother Charter) and sniped parts of Southern Ming (yet another one), while slowly colonizing my way up towards Alaska, waiting on the Europeans to colonize the eastern seaboard.
By the time 1650 came around i started my declerations on Europe. taking GB and their colonies (Thierteen and Colombia) in 4 wars, and sniped OPM Denmark (Nordjylland) and 2PM Norway (Iceland) before i made short process of Sweden in 3 quick wars, only made interesting due to Swedish having their OP Military ideas and Quality/Offensive. But even that can't cape against three times the military and a much deeper Manpower pool. Somewhere around here my economy also started to be strong enough that i could keep 8 colonies going, which made it much easier to expand them, now that there was very few colonizers. only England, Portugal, Spain and later on Netherlands and Leon ever colonized. France only took Exploration at 7th, and as far as i can tell never colonized anything, and none of the usual colonizing minors ever got around to do it either.
