Posting this here due to steam comments being dumb with character count.
Heyo, a few ideas for long-term stuff:
1. NPCs drive cars. Possibly using the power of modded java files and/or Teleporting vehicles through unloaded cells?
2. NPC personalities would include item/clothing preferences. For example, NPCs with the police occupation/spawn-loadout would gain a happiness boost or something when wearing/using police clothes and weapons. I suggest this one mainly because old habits die hard, and wearing a uniform every day would definitely be a hard habit to kill, even in a zombie apocalypse. (please add a way for other modders to add custom items to this concept, possibly through a new item tag?)
3. Possibly a "Day 0" option? Think the DayOne mod, but less grief, and more fitting to the game's lore? Basically have a few early game factions.
* Looters and/or Rioters. Would essentially be running around smashing windows and attacking police officers.
* Police. Would try to keep the peace. Think defending important buildings (Police Stations, Courthouses, etc) with methods that get more drastic as the day continues. Starting with Nightsticks, they'd eventually move on to firearms. While at the same time possibly escorting firefighters and EMS?
* Military. Wouldn't pop into civilian areas until later into day 0, the military would be police on steroids. Starting with firearms on spawn. Possibly have integrations for "Fort Redstone"? So that they spawn there and not just at the military checkpoint?
* Firefighter. Would serve a very minor role of spawning at those burnt house events. With a loadout of a fire extinguisher and other fireman gear. AI would be the same as Civilian, essentially.
* EMS (Ambulance Driver). Would Essentially just be a "pointA-pointB if you could get vehicles working with these NPCs. Driving from their spawn to the nearest medical center, then their AI would change to Civilian.
* Civilian. These fellas would basically defend their spawn building. Eventually exploring the brave new world around them after the first few days.

4. Possibly have 3. hook into the player's occupation? So players with the police occupation would start in the police NPC faction. I don't expect much here other than NPCs and players with the same occupation starting out friendly with eachother.
