This concept is cost prohibitive and even as a late game idea, would only be available to top tier players who likely already have their strategies set. I think TACRfan pretty much hits the points.
This game doesn’t flow like most games. It’s less competitive and more collaborative, thus the donating coins option recently released.
I can see someone wanting to combine stations down the road, more likely beginning or middle play. IRL, the US has many Public Safety Complexes that house all services. A simpler plan seems appropriate.
Three fully built out regular stations (Fire, Police, Ambulance) would allow for a total of 120 Bays (40 each) at a total cost of 11,380,000 Credits; far less than the 16,800,00 credits and would have 55 more bays than this concept.
Might I propose two alternative ideas? One is a new build and one combination of existing builds. As always, I’m not a coder so bear with me on how easy this is to do. I don’t know how the UK system has been set up.
COMBINATION OF EXISTING STATIONS - PUBLIC SAFETY COMPLEX
-1,000,000 credits per station combined, no limit. (2)Stations = 2,000,000, (3)Stations = 3,000,000, etc
-50,000 per existing Bay. Instead of a finite number of bays set at the beginning, you’re literally combining your station’s existing bays for a price.
-Any new bays are the standard 100,000 per pay.
-120 Bays maximum
-Expansions carry over. If combining a fire station with an ambulance expansion and an ambulance station, you lose that expansion.
-Carries the equivalent of 2 stations per mission type (Don’t need 100 trucks for a car fire)
NEW BUILD - PUBLIC SAFETY COMPLEX
-3,000,000 Credits to build.
-Fire, Ambulance, and Police available immediately.
-3 Bays included (Theory of housing 1 Fire Truck, 1 Ambulance and 1 Police Car)
-100,000 for any new bays up to 120. No discounts for the first couple bays, they’re included.
-120 Bays maximum
-Carries the equivalent of 2 stations per mission type
Any inconsistencies between the two ways of building are part of the strategy. Combining may cost more, but if you start with two, then three, or maybe leave it at two, it will allow building more credits to buy more. How and when is a part of the game and leaves those decisions to the player.
