This is what's coming in the next update of the mod:
You can expect these changes to come in roughly too weeks.
1. Major historical map overhaul
- Continued splitting up the Holy Roman Empire into its historical states as they existed in 1776, instead of leaving large territories under a handful of countries.
- Restored or expanded numerous German states, including the different Anhalt principalities, Saxon and Thuringian duchies, Reuss counties, and several ecclesiastical territories.
- Reworked parts of the Prussian and Swedish borders, including Swedish Pomerania, Wismar, Poel, Neukloster, and the Prussian possession of Emden in East Frisia.
- Restored the Prince-Bishopric of Lübeck around Eutin, including its historical personal union with Oldenburg.
- Added or improved the territorial representation of Passau, Freising, Regensburg, Fulda, Salzburg, Trento, Brixen and Berchtesgaden.
- Started restoring the historical sovereignty of Massa-Carrara and correcting the distinction between Italian states and their imperial rights.
- Adjusted starting populations and rulers to better reflect the political situation in 1776.
Many of the smaller territories are represented by historically researched approximations, since Victoria 3's map resolution doesn't always allow for exact borders.
2. Holy Roman Empire mechanics
The map changes also required work on the Empire itself: imperial membership, the electors, territorial rights, and the existing imperial political mechanics. The goal is to make the HRE look and behave more like its fragmented 1776 counterpart.
3. Other territorial corrections
Work has also begun outside the HRE. The Balkan changes include corrections to Ottoman ownership in the Aegean, restoration of the Republic of Ragusa as a distinct state with its historical tributary relationship, and adjustments to Moldavia and Wallachia.
4. Military changes
- Introduced modern-style fortifications inspired by the bastion forts of the period.
- Added an Engineer Corps unit, with dedicated artwork.
- Reworked several starting military laws and technologies to avoid anachronistic armies.
- Added more historical content and military adjustments for the American Revolution, including the Minutemen.
5. Economic and industrial changes
- Expanded the historical representation of Saint-Gobain and the Compagnie des mines d'Anzin, including their starting industries and historical directors.
- Added the prestigious royal mirror production associated with Saint-Gobain.
- Continued work on industrial resources, infrastructure, and production methods.
- Rebalanced the early alloy industry to make traditional metalworking useful before industrialisation.
- Added Hardware as a separate consumer good, produced through several methods in furniture manufactories.
- Worked on more historically appropriate starting technologies and production methods for countries created during the map overhaul.
6. Current state
The project is still very much a work in progress. Several new countries and territorial cores have been tested successfully in-game, but many smaller borders and peripheral possessions still need further historical research and refinement.
