What Would the TL of "Risk" Be?

So Risk is a wonderful board game but the world setting is a vaguely defined ahistorical. It's a Napoleonic Era World War of massive space filling empires vying for global conquest. This is clearly overthinking it, but what would the timeline of this world be?
 
As a kid my concept was:
The United States unified all of North America.
Bolivar unified all of South America.
Napoleon unified all of Europe.
The British Empire reigns over the remaining OTL territory.
Russia is Mega-Russia.
Super China or Japan rules the rest of Asia.
A superpower of some kind rules Africa.
