The Fiscal Ship, explained by people who built a different budget game

What The Fiscal Ship is

The Fiscal Ship is a free browser game about the United States federal budget. It is a joint venture of the Hutchins Center on Fiscal and Monetary Policy at Brookings and the Woodrow Wilson International Center for Scholars, and it was built by 1st Playable Productions. Its own description is one sentence long: make your own plan to keep U.S. debt from rising.

That sentence undersells the design. The Fiscal Ship starts with values instead of arithmetic. Before you touch a tax rate or a spending line it asks which goals you want government to pursue, and only then hands you the policy cards. A carbon tax earns credit toward fighting climate change and loses credit toward cutting taxes. The argument starts before the first number moves.

The game has been used as a teaching tool long enough to have its own classroom guide, published by Brookings. Its policy scores are built from Congressional Budget Office, Office of Management and Budget, Social Security Administration and Urban-Brookings Tax Policy Center estimates. This is not a quiz with a budget skin.

How a Fiscal Ship run works

The opening screen asks players to choose up to three governing goals. The eleven available in the version documented by Brookings are: reduce inequality, strengthen national defense, fight climate change, strengthen the social safety net, tax cutter, shrink government, protect the elderly, invest in the future, fiscal hawk, rein in entitlements, and a slate of sitting-president priorities.

Players then choose from more than 100 tax and spending policies. Each policy has a card: a short explanation of what it does, the arguments for it, and the arguments against it. There is no fixed number of policies to pick. You keep choosing until the debt line reaches the sustainable path and your goal badges are satisfied.

Winning has two halves, and both matter. The debt-to-GDP ratio 25 years out has to be no higher than it is today. And each governing goal you chose has to earn three stars. A plan that stabilises debt while abandoning every value you started with does not win.

The interface keeps the debt path on screen while you work. Hovering a policy card draws an orange line showing what that card would do on top of the policies already chosen. A “View my plan” panel tallies how many policies you played, how much revenue you raised, how much spending you cut, and whether each choice moved you toward or away from each goal.

The debt target has moved with the projections. When Brookings set the goal it was 75% of GDP in 2041, down from a projected 126%; by the 2019 classroom guide the rule was expressed as debt no higher in 25 years than it is today. Because the game is updated when the CBO publishes new projections, the goal screen is the authoritative number.

Brookings reported that players who stay past the first few seconds spend about 15 minutes in the game, that roughly 70% play on Windows, Mac or Chrome OS and about 30% on iOS or Android, and that the game attracted 22,800 users in April 2019. An “In the News” basket keeps current policy debates on the board.

What it gets right

Three design choices are worth copying. The first is values first: asking for goals before policies forces the player to admit that a budget is a statement about what government is for, not a maths problem with one answer.

The second is the policy card. A short explanation plus the strongest argument for and against each option is better civic education than a paragraph of neutral summary, because it shows that reasonable people disagree about the same number.

The third is the scoring anchor. The Fiscal Ship does not invent fiscal effects. It starts from official estimates and extends them beyond the ten-year window as a share of revenue, spending or GDP. When a game borrows the real estimators’ numbers, the argument after the game is about values rather than about whether the numbers were made up.

The classroom material is unusually complete: suggested player profiles, group formats, and a discussion path that starts with the debt, moves to values, and ends with a plan.

Where it stops, by its own account

The Fiscal Ship’s guide is candid about two limits. Its policy scores are static, not dynamic: they do not include the effect of policies on economic growth. The authors explain why — dynamic scoring is difficult, subjective and open to political bias — but the consequence for the player is that a growth-friendly investment and a growth-damaging tax cut are scored on their direct budget effect alone.

The second limit is interaction. Each policy is scored on its own; the game does not recalculate what a deduction is worth after you change the tax brackets around it. In a plan with a dozen policies, those interactions are part of the real argument, and the game leaves them out.

There is also a scope limit. The Fiscal Ship is a 25-year US federal budget path. It is not a month-by-month political simulation: the documented loop has no parliament to negotiate with, no censure vote and no bond auction repricing your debt while you decide. It is a plan you build, not a term you survive.

None of that makes it a bad game. It makes it a different instrument: a values-driven budgeting seminar rather than a term in office.

Budget Battle and The Fiscal Ship, side by side

Budget Battle is the game on this site. It is an independent browser game set in a fictional euro-area economy, and it was built around the parts of the job that The Fiscal Ship deliberately leaves out: the politics and the market. The table compares the two on the dimensions a player actually notices.

What the table means in practice

Read it as a choice of instrument, not a ranking. The Fiscal Ship is broader in policy coverage and anchored to official US estimators. Budget Battle is narrower in policy count and deeper in consequences: each measure spends political capital and moves growth next season, and the bond market reprices your credibility every month.

The two games also answer different questions. The Fiscal Ship asks “what would I cut, and what kind of country do I want?” Budget Battle asks “can I get this through the room, and what does the market do to me if I get it wrong?” The first is a plan. The second is a job.

Who each game is for

Choose The Fiscal Ship if you want to understand the US federal budget, if you are teaching a civics or economics class built around US institutions, if you want more than 100 real policy options with sourced scores, or if you want a fifteen-minute exercise that starts from values.

Choose Budget Battle if you want to feel the job rather than the spreadsheet: five seasons of twelve monthly episodes, five spending ministers, a parliamentary vote in December, a bond yield that reacts to your credibility, and a score you can compare on a public leaderboard. It is also the better fit for players who want Spanish or French, or who want a game that is explicit fiction rather than a forecast about one country.

Play both if you are teaching. The Fiscal Ship shows students the size of the US fiscal gap and the trade-offs between goals. Budget Battle shows them why a plan that looks fine on paper can fail in a room with five ministers and a bond auction. The two lessons are complementary, and neither game is a substitute for the other.

The short version

The Fiscal Ship is a serious, free, well-sourced game about the US federal budget. It asks you to pick up to three goals, choose from more than 100 policies, and bring the debt path back to today’s level within 25 years. Its scores are static and its policies do not interact, both by its authors’ own account.

Budget Battle is a free browser game about the same underlying problem — a government spending more than it collects — compressed into a five-season mandate with political capital, popularity, a bond market, a December vote and a leaderboard. It is not a copy of The Fiscal Ship, and it is not a replacement for it.
