There should be events encouraging the following wars, all with certain requirements for them to fire-
-World War I (there should be events setting up the Entenete and Central Powers, but they shouldn't necessarily end up the same way every time)
-Civil War (American, this should depend on earlier decisions as it did in Victoria I)
-Crimean War
-Russo-Japanese War
-Boer Wars
-Lots more civil wars like the War of the Farrapos, Taiping Rebellion, etc.
-Franco-Prussian War
There should also be events regarding-
-The Partititon of Africa (instead of it ending up exactly like it did, the colonies and the nations that receive them should depend on how powerful and well-liked each European candidate is, and what areas in Africa they have greatest presence in, not on who got the colony historically)
-Freeing of slaves in many nations (like Brazil), but with more random dates.
-White immigration to places like New Zealand, Canada, etc.
-Unification of Germany, Italy. Very likely to turn out historically.
-Unifications of La Plata, Gran Colombia, Scandinavia, and Peru (including Chile and Bolivia), and reunification of USCA. These would be less likely to succeed.
-Spread of Christianity in the colonies.
-Granting of dominion status to certain colonies. These dates wouod be greatly variable and would rely on population (of accepted cultures), unrest, etc.
Every single event should have some date flexibility, at least one prerequisite, and choices for the nations involved. Even rebellion events should have choices determining how harshly to react.
Basically, if they just copied alot of the events found in VIP, maybe with some touching up, that would be great. Although with some of the less-significant events taken out and some important ones (like leading up to WWI) added in.
