I tested this to the game ends. No one builds anything,

Step 5 Assign alliances

There will to be two alliances "Aggressor" and "Status Quo" The Aggressor alliance is attempting to reorder the world through military force, while the Status Quo is trying to resist that.

As I am not trying to track the ideologies you can assume that unlikely alliances are probably the result of ideological conflicts and similarities.

The first step is to determine the lead aggressor. The lead aggressor is randomly chosen from the major countries. The lead aggressor goes first and will receive more units.

Next the lead status quo power is chosen from the remaining major countries. The lead status quo power receives extra resources.

The remaing major and medium powers are randomly assigned as follows

The "Victim" nation is a passive member of the Status Quo alliance. It is neutral with regards to the rest of the Status Quo alliance and at war with the Aggessor alliance. The Status Quo alliance can't assist the "Victim" but if the liberate a territory they don't need to return it. Each turn the lead Status Quo power receives a bonus of 1 PU for every Victim-held territory. Note that is major or medium power has been reassigned to the victim nation, that means it is in civil war or some other internal disorder.

The "Impassable" nation is neutral to everyone and out of play.

There is a 50% change of delayed entry of each Status Quo nation and a 25% change of delayed entry for each Aggessor nation (other than the lead aggressor). The delayed entry nation comes in a randomly chosen turn between 2 and 5 at the start of the lead aggressor turn. It is possible that every Status Quo nation is delayed entry, allowing the lead aggessor to focus on victims.

Historically, there was one territorial dispute directly involving major & medium countries, Alsace-Lorraine. Ethnically German but historically French it would be difficult (but not impossible) to resolve the dispute and conflict is likely. There will be a 30% chance that Germany is lead aggressor, while France is a status quo power that is active immediately. This will probably not work out well for France.

Step 4 Align minor countries with larger countries

As minor countries don't have their unit images or turns they will be aligned with medium and major countries. Medium countries will also sometimes be aligned with major countries.

When countries are aligned, their territories and units become part of the larger country, like Canada with Britain in the original game.

Each minor and medium country will be entered into a table giving their chances of being aligned. In addition, countries may be aligned into the dummy countries of "Victim" and "Impassable".

Note that this may in effect undo step 3. For example India may gain independence in step 3 and become a close ally of Britain in step 4. The effect will be the same, but the notes will be different.

This is also when protectorates are handled. Egypt will be probably be aligned with Britain, but it may escape British control and be aligned with some other country.

If China has become aligned with another country, then the special Chinese rules don't apply.

Step 3 Resolve Interwar Period

There were a number of conflicts in the interwar period which could change what country controls a specific territory. Most only involved a single territory such as the Rif War or the Indian Independence movement. Territories controlled by the "Split" country must be assigned to a specific country.

There are three conflicts that deserve special consideration, Russian Civil War, Russo-Polish War and the Reunification of China.

Russian Civil War In the context of this scenario generator, it does not matter which side wins as somebody will end up controlling the core Russian areas of Russia, Archangel and Karelia. However there was a possibility of creating a stable country in Siberia controlling multiple areas. Peripheral areas of Russia may gain independence.

Russo-Polish War as closely related to the Russian Civil War. Plausible outcomes range from Russian reconquering Poland to a powerful Polish state controlling Poland, East Poland, Baltic States, Ukraine, East Ukraine and Belorussia. However the outcomes must all involve a contiguous Polish state. Note that even a maximum Polish state remains a minor country.

The order of resolution needs to be

War of Chinese Reunification By the end of WW1, warlords have already taken control of China. In effect each territory was an independent state. If the Northern Expedition had failed, China would have remained divided.

An additional complication was the Japanese invasion. The Japanese may decide not to invade, to only take Manchuria or to take Kiangsu as well. Note that if the Japan and China end up on the same side, Kiangsu will be returned to China.

Even if China is reunified, there still be independent states formed, representing undefeated warlords or Communist territory. There is also a chance that Kwangtung ends up under effective Chinese control.

In any case the usual China build rules and territory restrictions apply, as the KMT would not even under the best of circumstances had enough time to build a modern industrial economy. If China is allied with Japan, than the movement restrictions are China are lifted.
