Units drive the streets
Apparatus leave the station and take the roads. A motorway detour beats a slow direct lane exactly as it would in a car, and the drive is the wait.
Build fire, EMS and police departments over actual OpenStreetMap streets. Calls come in at real addresses, your apparatus drive the real roads to get there, and what happens when they arrive depends on who you sent and how long they took.
Most management games abstract the map away into a list of jobs and a timer. Here the geography is the game: where you put a station decides what you can reach, and how far the nearest water is decides how many tankers you need.

Every job comes in on a named road in a named town, and no two medical calls on the same street are the same job.
Casualties are unknown until somebody physically arrives, trapped patients cannot be treated until a rescue unit cuts them out, and the payout scales with who survives.
Volunteers live at real addresses near the station, drive real routes in when you page them, and go home again if you do not use them. The same person is always the one who takes four minutes.
Departments are tax funded rather than paid per call, so stations are the growth lever and a truck you cannot crew is a net loss. Found the ones you want, in the order you want them, and live with the gaps until you do.
Eight apparatus types, none of them decoration. Engines, aerials that also extricate, a brush truck that is far better on wildland, and tankers that shuttle water when the nearest hydrant is a field away.
BLS and ALS, stretcher limits that make a six casualty scene a different job, medic fly-cars that intercept a transporting ambulance partway, and hospitals you site yourself.
Patrol, K9 that turns a long grid search into a short one, supervisors who run a scene faster, detectives, and the one unit an armed barricade will accept.
Tuned against Loyal, Wisconsin, a village of about 1,200 people with a volunteer fire department, which is what most of the country actually looks like.
Every unit is drawn to be told apart at a glance on the map, and lit so you can pick the one that is responding out of a street full of them.
The roadmap is the real one, not a wishlist, and the board is where bugs and suggestions go. Your account carries your department between devices and signs your posts.
