This page talks about a mode which is optional for any war based match made, where it is to make it feel more realistic. It talks about the faction's actions being reflected on the their own local or conquered populace or land.
This section is where we talk about a faction's local and/or conquered population, whether they are content or unhappy, regarding it's social, demographic, cultural, economic, etc. influence.
The Population can also determine the continued effort for any long term wars, drafting, breeding, populating, constructing, etc.. Numbers are one of the determining factors in conflicts.
This section is about the faction's production capabilities in order to support their nation/organization/species and to be able to fund the war efforts against their opponents. This would include consumption of natural resources, diverting treasury to the war or organizing trade with anyone.
Economy is another vital role for when fighting a war, as it is important to know what to spend and what not to spend, another option (if there is any information) is to know how much money do an organization/nation has to spend and/or how much certain units cost to employ.
This section can likely be added to the Civilization Tiering Setion.
This section is about the faction's policies that they enforce onto the population that they control, whether they are to make them feel free in an unhappy setting, or enforce stronger authority in a lawless society.
This section is where factions will form some sort of relationship with one another, whether it would be alliances, confederations, wars, trade agreements, or forming vessel/states states. This can be depending on what the end goal is for the crossover war scenario in question.
This one maybe subject to change or edits depending on people's opinions on this in the OP of a thread. This may play a role in War Scenarios when created.
Having allies is also important when fighting battles, it gives you a sense of not being alone.
