Overview

Nonpartisan U.S. Presidential and macroeconomic simulation at gsim.ngi.video where you govern across 32 quarterly turns inside a layered vintage Americana Oval Office—drafting quarterly task-force perks, stacking Policy Doctrine combos, coaching your moves against a same-seed Autopilot baseline, and seeing how fiscal and tariff choices change monthly family budgets.

Why it was built

Most political games treat governing as simple partisan sliders with no strategic feedback, leaving players guessing why their economy trailed doing nothing or how tax rates, spending bills, and interest rates affect real households.

Why it helps

Shows a live Beat-the-Baseline score preview and Chief of Staff playbooks before you end each quarter, tracks pending bills and crises on a stacked index card, and translates federal policy into monthly household dollar impacts.

What you can do

  • Beat-the-Baseline Strategy Coach with live score-delta previews and rotating three-path Chief of Staff playbooks
  • Layered vintage Americana Oval Office with borderless pill-pawn character rigs, manila folder tabs, and optional Dark Americana Evil Mode
  • Quarterly task-force perk drafts, Policy Doctrine set bonuses, and a stacked turn agenda card tracking clearing bills
  • Kitchen-Table household dollar calculator, spectrum-balanced Civics Myth busters, and full parameter Model Inspector at gsim.ngi.video
