World Domination

World Domination is the penultimate era and the first with a genuinely brutal gap at the end of it. Its three buildings — Greenland, the Space Force Fleet, and Planetary Annexation — are the last "Earth" buildings, and the jump to the final era is six orders of magnitude instead of the usual three. Plan for a real climb.

New buildings this era

Base values for the first copy. Each additional copy costs 15% more, and the 10 / 50 / 100-owned upgrades multiply that building ×3 / ×5 / ×7.

Global upgrade unlocked

Zero-Gravity Tariffs (1e27 MAGA$) — ×3 to all production.

Strategy

Note the spacing change: within this era the last few buildings are already stepping ×100 apart instead of ×10, and the gate to the final era sits far beyond Planetary Annexation. Brute force alone will crawl. To close the gap you want every multiplier the game offers working at once — all globals bought, a wide Weaponized synergy base, a healthy Mandate stack, and a full shelf of achievements each adding their +1%.

This is the strongest argument in the game for prestiging before the final push if you have points banked. A big Mandate bonus turns the six-order-of-magnitude gap from an overnight idle into an afternoon of active play. The strongest events also live here: Greenland, Acquired (a 30-minute lump sum), the Presidential Hover Throne (×9 frenzy), and Flag Day (a 33-minute lump sum). Bank a couple of these near the gate for a final shove.

Side quest

Side quest: Annex Everything — plant 51 Flags for the "The 51st State" achievement. (This is the game's longest quest bar one; the falling-star state collection to 50 runs alongside it.)

Reaching the next era

54 octillion (5.4e28) lifetime MAGA$ opens the final era, To The Moon, and the last global, Helium-3 Monopoly.
