So, since you guys jumped from the tutorial level to the medium level to DARK SOULS MODE I've decided I'll actually get around to explaining how money works.
First, it needs to be clarified that the monetary pool isn't a fixed and finite resource. It ebbs and flows, depending on the mood of High Command and the Civil Government.
Second, your monetary pool is a diminishing resource. Every turn, it goes down depending on how your votes go. This is from the static costs of running an office- paying the telephone and telegraph bills, buying postage, filling the coffee pots, and leaving the night light on.
Third, the rate at which your money pool diminishes depends on your votes. Big plans that do a lot cost more than small plans, and complex line items cost more than simple line items, and line items increase in cost according to an exponential growth formula that starts kicking you at about line seven and aims for the balls at ten. If your line item has a period to diffferentite a new sentence, then that's an extra kick in the budget. Most of this is due to the need to pay overtime, send telegrams versus telegraphs, hire couriers, use the Staff Car, take long-distance calls, and pay stenographers.
Fourth, testing will eat your budget alive. If you plan on having two test trials, get ready to skrimp and save everywhere else, because time and money are tied together real damn tight. Try to spend more time, spend less money. Spend more money, spend less time. Spend any time using a testing ground (where a lot of units get broken in since training grounds are expensive as hell) and you're gonna end up bleeding cash at a stiff rate.
Fifth, leftover money and personal funds can't be spent on projects. This isn't the Early Modern Era, boyos.
