Municipal deposit
How many upgrades does the municipal depot require before the cost of increasing it rises in SimCity?
For example, the first upgrade costs 1 of each item (bars, padlocks, and cameras). At what point does it start requiring 2 of each item? Does this pattern persist for all upgrades, such as increasing by 1 additional item every three upgrades for example?
I also wanted to know if there is a limit on expansions of the municipal deposit.
