So I had this really unique idea on the fire side of the game.
Create a “Volunteer Fire Station” for the game.
How it works: The volley station could be constructed for someone where between 200-300k and would be expanded the same amount of times as other regular stations. The only difference is when an apparatus is stationed in a Volunteer station, it requires volunteers to operate. So instead of “hiring” staff, there is a timer for units to come to the station and operate.
Example.
brush pile- 1 volley engine, requires 2 members. 1 minute per member to get to the station.
This could be a more “coin efficient” way for players who don’t want to have to spend 5 coins on each new member. It would substitute the coins for your time since a normal brush pile mission can take like 3-4 mins, and it will now take 7-10 mins due to the wait time of the volunteer firefighters.
