Victoria 3 — The Great Wave and patch 1.13 Matcha

Victoria 3's second major expansion

On April 28, 2026, Paradox Interactive launched The Great Wave, the second major expansion for Victoria 3. The expansion focuses on two main axes: a complete rework of naval mechanics with the Ship Designer, and dense narrative content centered on Japan's Edo period and its transition to the Meiji era. The free base game patch 1.13 'Matcha' accompanies the release with deep changes to the naval combat system, characters and diplomacy.

The Great Wave arrives after Sphere of Influence (June 2024), which introduced diplomatic Power Blocs. This time the theme is firmly maritime and Asian: 90+ modeled historical characters, a full Bakumatsu journal entry with three distinct possible outcomes for Japan, and naval mechanics that deeply transform how great powers project influence on the world stage.

Ship Designer — Building your fleet block by block

The Ship Designer is The Great Wave's mechanical centrepiece. Each ship is now an individual object that can be built, damaged and sunk. Players customize loadouts across four categories: Armor (hull color and portholes), Armament (number of cannons), Propulsion (smokestacks or masts), and Supply Capacity. Twenty distinct ship types are available, each with its four visual customization categories.

Flagships add a prestige layer: only one ship per fleet can receive this status. It gains or loses prestige based on battle outcomes and can be adorned with a customizable figurehead. The Naval Administration building provides crews, and the reworked naval combat introduces Initiative values, hull and crew damage, and a 'battle circle' for engagements.

Edo-period Japan — Bakumatsu and Meiji Restoration

Japan's narrative content is The Great Wave's editorial highlight. Starting Japan is under the Tokugawa Bakufu with the restrictive Edo system. The 'Honorable Restoration' journal entry covers the Bakumatsu period (1853–1868) with two rival factions: Sonnō Jōi (Revere the Emperor, Expel the Barbarians) and Sabaku (Support the Shogunate). Three outcomes are possible based on player choices: Union of the Court and Shogunate, Parliamentary Government, or Full Imperial Restoration (the historical outcome, with likely civil war).

Key events include the Tenpō Crisis, the Iwakura Mission (diplomatic expedition to learn foreign political systems), and the Sakoku law for isolationism. The region is enriched with specific content for Ryukyu ('The Hidden Domain'), Hokkaido ('Taming the North'), Korea and the Zaibatsu ('The Corporate Empire'). In total, 90+ historical characters were modeled with identifiable visual DNA.

Gunboat Diplomacy — Naval power as a diplomatic tool

Gunboat Diplomacy adds new diplomatic actions that leverage naval power during treaty negotiations. Players can now threaten naval hostilities, directly devastate coastal states via the Port Bombardment mission, and sell ships to other nations through Ship Purchase Treaties to generate economic revenue.

The Straits system allows controlling strategic passages through Naval Fortifications and tolls. Strait control provides significant economic and military advantages for the powers that hold them, adding a new geopolitical dimension to the world map.

Patch 1.13 Matcha — Free changes for everyone

Patch 1.13 'Matcha' brings deep changes to the base game, free for all players. Characters get a new Prominence stat (political weight distinct from Popularity), a National Cast to avoid automatic purging, and a new Magnate role tied to owned buildings. Children no longer have ideology or traits before adulthood.

• Commanders: one per formation, travel time on reassignments
• Diplomatic interest: binary system replaced by involvement tiers
• Trade: route calculation avoids excessive tolls
• New law: Peasant Proprietorship (Homesteading variant)
• Hotfix 1.13.5 (May 12): balanced naval AI, ship XP system, MAPI fix

Pricing and availability — $39.99 CAD

The Great Wave is available standalone or in a bundle. Victoria 3 base game is required. Note that patch 1.13 Matcha, which includes the naval rework and character changes, is entirely free — only the Japan narrative content and naval cosmetics are reserved for expansion buyers.

Reception — Launch bugs, rapid hotfixes

Steam reviews for The Great Wave sat at 26% positive across 456 ratings at launch — 'Mostly Negative'. The main complaint: serious bugs at release, including armies getting stuck at sea and a dysfunctional naval AI. An unfortunately recurring pattern for Paradox, which has released several problematic expansions in recent years.

« We are aware of the issue with armies sometimes getting stuck at sea. A fix is coming in the next two days. »

— PDX_H4n1baL (développeur, Steam — 28 avril 2026)

Hotfixes 1.13.3 and 1.13.5 were quickly released and effectively resolved major issues. The May 12 hotfix 1.13.5 notably fixed the naval AI over-building Supply Ships to the point of ruining its economy, and introduced a crew XP system for ships. The Japan narrative content is unanimously praised by players who have access to it.

La Meute QC verdict

The Great Wave is an ambitious expansion that suffers from insufficient launch quality — a systemic Paradox problem. After the May 2026 hotfixes, the expansion is in a playable state and the content is substantial: the Ship Designer adds real strategic depth, and the Japan scenario is one of the richest ever added to Victoria 3. Players who waited a few weeks after launch had a significantly better experience.

For HOI4 players in our La Meute QC community, Victoria 3 shares the Paradox grand-strategy DNA but in a different era (19th century industrial vs World War II). The Great Wave's naval mechanics offer depth comparable to HOI4's naval systems, and the Japan focus speaks to an audience familiar with world history.

Who's it for? Who's not?

• For: Paradox grand-strategy fans who have Victoria 3 and enjoy naval depth
• For: players interested in 19th-century Japanese history and the Meiji period
• For: HOI4 players who want to explore another Paradox game with familiar mechanics
• Not for: Victoria 3 newcomers — buy the base game first and get comfortable before the DLC
• Not for: day-one buyers — wait for hotfixes, Paradox has a history of buggy DLC launches
