Suggestion: Add civilian rescue mission? Just like XCOM?
For example,
Carnivores/Herbivores/Humans are trying to start a massacre on targeted community to gain support from radicals, and your army is tasked with evacuating civilians?
Contact civilians by standing near them, then escort them to evacuation point either on foot, or with vehicular transport?
Add some civilians who are heavily armed with AK-74 and molotov cocktails, or lightly armed with TOZ-28 to resist the aggressors? Show the importance of having gun rights for civilians?
That would increase the uniqueness of the game compared to Advance Wars.
