Each Simyear, you have the opportunity to set the annual budget.
Simcountry is an unlimited free game, it runs five virtual worlds with more than 23.000 countries. It is both a strategy war game and a financial strategy game.
As a president and commander in chief, you are responsible for the army, its weapons and ammunition and for the quality of your Military Units.
If you forget to set the budget for the following year, or if you deviate significantly from your proposed budget, the consequences are minor at best.
The budget is supposed to be a guestimate for how much you are going to spend on each of the various items your country spends money on. It does not affect how much you can actually spend, or how much you actually will spend. Currently, budget is something best ignored.
