Yes, Ryu, if a small Iberian Nation is gonna be the first to colonize expect Major Differences.
The British might completely own the carribean.
Castlie might take the atlantic coast where OTL 13 colonies where.
Portuguese Mexico?
Aragon Taking Rio De plata?
French Brazi?
Dutch Terra Del Feugo
HRE Canada
Byzantine Orgegon
Morrocan Peru?
Kieven Alaska?
Genoan Bermuda?
Which one of these do you think are the Most ASB, which ones are the least?
They are extremely suggestive and equilibrated ( i like an colonial America with no wank colonies); i think the most ASB in the list is Byzantine Oregon , i guess you imaginated this expansion route:
Byzantine Egypt > holdings in India > South-East Asia or China and Japan > Hawaii > Oregon?
For Moroccan Peru i guess first they must estabilish control over Columbia.
Maybe the British could take Cuba and Santo Domingo but as IOTL let the Minor Caribbeans divided between the mayor colonial powers; let them to have an haven after Atlantic crossing and before they go to their continental holdings.
Spanish USA?
For any eventual Dutch expansion it depends when and how much of Netherlands seceded from HRE ( suggestion: maybe this time could be Belgium to promove the indipendence fight?)
Kievan Alaska... so it could only be...
For HRE colonial ventures first i guess they renew their fleet and hold more ports over the North Sea... so we return to the question of Dutch indipendence... Maybe an HRE Amstedam offered best chances? Also if you want a HRE Canada... maybe first they must seize the Orkneys to avoid the passage from English Channel?
