Random New World

The default settings are enough for a first campaign. Everything else on this page can wait.

1. 1

   Open the generator

   In EU5, open Mods & DLCs, find Random New World (RNW) and click Open folder. Launch Random New World Generator from that folder.

   Once the generator is open, you can close EU5 to free memory.

   

2. 2

   Choose a world

   Click New world and pick a World type on the World tab. Continents is a good first choice. Leave the rest as it is, or paste a friend's World code.

   

3. 3

   Generate it

   On Save and play, keep Keep the mod in the library and tick Add to the game when it is done. Click Generate and wait a few minutes.

   Generation needs about 7.5 GB of free RAM.

   

4. 4

   Enable it and play

   In Mods & DLCs, tick your new world, for example RNW: Small continents 7K3Q, click Apply and start a new 1337 campaign.

   Leave Random New World (RNW) itself unticked: it only holds the generator. Your world mod contains everything the campaign needs.

   

A world type is a starting set of settings. Choose the shape you like, then adjust it on the World tab or in Advanced.

• 

  Supercontinent

  One great landmass across the New World, with a few islands.

• 

  Continents

  Large continents, often joined by isthmuses as the Americas are, and islands.

• 

  Small continents

  Three or four separate continents of similar size.

• 

  Archipelago

  Five to eleven large islands and many small ones: a world of ships.

• 

  Scattered islands

  A sea full of small islands, with no great landmass.

• 

  The Wall

  A straight north-south continent with a mountain spine and side land. Procedural shores may form islands and narrow straits when gaps are allowed.

• Random One of the world types, drawn at random when chosen and at each press of Random. The Advanced values are those of the type drawn.
• Total Chaos A world type drawn at random when chosen, and every Advanced value drawn at random within its playable range.

With Allow gaps in the wall turned off, the Wall becomes one continuous barrier that ships can neither cross nor sail around.

Every value still makes a playable world. These are the controls worth knowing; Reset all to the world type undoes your changes.

Seed and World code

The seed picks the world, and Random draws a new one. A world code holds the seed and every setting: copy it to share a world, paste one to make it. The same code makes the same world with the same generator release and game files.

Choose a continent

Shows six land sketches before you build a whole world. Pick one to take its seed and settings. Sketches reveal the land, and the final coast can still shift a little.

Your own continent

Save template gives you an image of the area to fill. Paint land white and sea black, then load it with Land from an image. Relief, rivers and peoples are generated on your outline.

Expand generation into the oceans

On by default: continents get room beyond the old outline of the Americas. Raise Distance from the Old World in Advanced to move the land toward the middle of the ocean.

Native societies

Native states on the World tab is the quick choice. In Advanced, Land in states sets how much inhabited land states hold (3–60%), and Peasant share caps the share of peasants in a settled location (30–80%). Poor farmland stays more tribal.

Resources

In Advanced, each resource has its own frequency: 1× is the base game, 0 removes it. More of one leaves fewer locations for the others. Climate and terrain still decide where each one can appear.

New worlds start covered. Country selection shows Terra Incognita in place of the New World, and you can still pick a native country from the list.

Reveal this world

Uncovers the world's maps inside the generator. The game keeps its own setting.

Show the New World before you play it

Uncovers the mod picture and the country-selection map in EU5. Set it on Save and play, or later on the world's World tab without generating again; then close and reopen the mods menu.

A revealed world opens ten maps under Maps: land, countries, cultures, religions, resources and more. Compare sets two worlds side by side.

Everything you generate stays in the generator's library, with its code, maps and notes.

Create a version

Select a finished world. New peoples makes new countries, cultures and religions on the same land; New resources draws only the resources again. The earlier version stays in the library.

Several worlds in a row

Add to queue keeps the current settings as a job, and Run queue makes the worlds one after another. You can add more while one is generating.

Share a world

Send the world code, or Save world file for a .rnworld file with its maps and notes. Your friend makes the playable mod from it with their own game.

Move a world between your computers

Transfer built world saves the whole built mod as a .rnworld-mod file to carry to another of your computers. Both need the same game version.

Clean up

Remove takes worlds out of the game and keeps their records. Delete deletes them for good.

Game version

EU5 1.4.*. New patches of the 1.4 branch usually work without a generator update; last fully verified on 1.4.7.

Saves

New campaigns only. Updating the generator does not change existing worlds or their saves.

Across the Pillars

Supported and optional. New World expeditions and treasure fleets use the generated map.

Refined Colonization

Compatible. Load order: Refined Colonization first, then your world mod.

Multiplayer

Supported and tested by the community. Every player needs the same game version, world mod and other mods.

Ironman and achievements

Work under the standard game rules.

Map overhauls

Mods that replace the Americas conflict with RNW. Other combinations are untested.

System

Windows, or Linux and Steam Deck through Proton. macOS is not supported.
