In the case of a Europe-screw with minimal impact on the rest of the world (any suggestions for POD?), how might borders develop in Africa, Asia and the Americas?
European colonialism does not need to be entirely avoided, but it would be preferential to reduce it as much as possible. Have more Hong Kong’s and less Indochina's, for example. Or Goa and Pondicherry, but not the Raj. Bonus points if colonialism is reduced as much as possible from non-European countries, so no China industrializes and making the whole world it’s tributary.
How might the world develop with independent Incan Empire in the Andes, the Empire of Vietnam dominating Indochina, etc.
