I notice you're asking about RimWorld version 1.4.3901 (likely a typo for 1.4.3901, as 143901 doesn't exist) with all DLCs — specifically Royalty, Ideology, and Biotech.
Here's a straight answer:
Yes — that combination is widely considered excellent content. Here's why:
It is a fair question. RimWorld's Update 1.5 introduced new anomalies and horror elements. So why stick with Build 143901?
Without the other DLCs, Royalty simply adds psychic powers, a medieval-style Empire faction, and the title system. In Build 143901 with all DLCs, Royalty acts as the political skeleton. Your Biotech-created mechanitors can now also be nobles. Your Ideology's high priest can wield a Persona weapon. The psychic amplifiers from Royalty become a status symbol influenced by your colony's religious beliefs.
First, let’s address the keyword. In software development, a build number (like 143901) represents a specific snapshot of the game’s code. For RimWorld, this build corresponds to a stable, post-release patch that includes significant bug fixes, performance optimizations, and—most importantly—full compatibility for all existing DLCs.
Unlike newer experimental branches that might introduce instability or mod-breaking changes, Build 143901 is widely regarded as the "Goldilocks" version of RimWorld. It is new enough to include the latest mechanics, but old enough to have a massive library of compatible mods. When paired with "all DLCs full," you are looking at a game that has reached critical mass in terms of content density.
Bottom line: If you have RimWorld 1.4 + Royalty, Ideology, and Biotech, you have one of the deepest colony sim experiences available. Worth every hour.

The Odyssey of New Eden - 143901
It was the year 143901 on the unforgiving planet of RimWorld, a distant world on the edge of the galaxy. The once-thriving colony of New Eden, founded by a group of space-faring pioneers, had seen better days. After a string of unfortunate events, including a brutal raider attack and a debilitating psychosis outbreak, the colony teetered on the brink of collapse.
The player, a grizzled veteran of RimWorld's harsh environment, had been tasked with leading a new group of survivors to the beleaguered colony. Their ship, the "Aurora's Hope," had limped into the planetary atmosphere, dodging deadly solar flares and rogue asteroids along the way.
As the survivors disembarked, they were greeted by a desolate landscape. The colony's once-manicured gardens had withered and died, while the buildings stood as a testament to the ingenuity and desperation of their predecessors. The air reeked of smoke, sweat, and desperation. rimworld 143901 all dlcs full
The player's party consisted of a diverse group of individuals, each with their own unique skills and scars. There was Jax, a former combat medic with a talent for patching up wounded flesh; Elara, a soft-spoken botanist with a green thumb; and Arin, a hot-headed engineer with a penchant for jury-rigging machinery.
Their first priority was to assess the colony's current state. The power grid was faltering, the food stores were running low, and the mental health of the colonists was precarious at best. The player knew they had to act fast to prevent a complete collapse.
With Jax's medical expertise, they set about tending to the wounded and establishing a makeshift infirmary. Elara got to work in the gardens, coaxing life from the barren soil and reestablishing a reliable food source. Arin, meanwhile, set to work repairing the colony's critical infrastructure, from the power generators to the life support systems.
As the days turned into weeks, New Eden began to show signs of life. The colonists, once on the brink of despair, now worked together with a renewed sense of purpose. The player had brought a semblance of order to the chaotic world of RimWorld.
However, just as things were looking up, a new threat emerged. A group of raiders, notorious for their brutality, had set their sights on New Eden. The player knew they had to prepare the colony for the worst.
With the help of their companions, they set about fortifying the colony's defenses. Arin crafted makeshift turrets and traps, while Jax and Elara helped to train the colonists in basic combat and first aid. The player, meanwhile, coordinated the colony's resources, ensuring that everyone was working together to survive.
The raider attack came on a fateful day, as the sun dipped below the horizon. The colony's defenses held strong, but the player knew that they couldn't keep this up for much longer. New Eden needed a long-term solution, not just a Band-Aid.
As the dust settled, the player looked out upon the battered but resilient colony. They knew that there was still much work to be done, but for the first time in a long while, they felt a sense of hope. New Eden would survive, and perhaps one day, it would thrive.
And so, the odyssey continues...
The player smiled grimly, knowing that RimWorld had many more challenges in store for them. But with their companions by their side, they were ready to face whatever the future held.
All DLCs (Downloadable Content) were active, which meant that the player had access to a wide range of new items, mechanics, and features. These included:
The full game, with all its DLCs, offered a rich and immersive experience, with countless hours of gameplay and storytelling possibilities.

version 1.4.3901 is a specific technical build within the 1.4 "Biotech" era of the sci-fi colony simulator. Released in late 2023, it represents one of the most stable and feature-complete versions of the game's previous major cycle before the jump to version 1.5 and the Anomaly expansion in early 2024. The Core Experience: What is RimWorld?
Developed by Ludeon Studios, RimWorld is an AI-driven story generator where you manage a group of survivors stranded on a frontier world. It blends deep survival mechanics with complex social simulation, tasking players with everything from building a defensible base to managing the psychological breakdowns of their colonists. The "Full" DLC Lineup
As of April 2026, a "full" version of RimWorld includes the base game plus five major expansions, often referred to by the community using the "RIBON" acronym: RimWorld Anomaly
RimWorld currently has five major expansions that significantly expand the base game experience. When playing with "all DLCs," these systems integrate to create a complex, multi-layered colony management sim. Core DLC Content Overview
The following expansions make up the full official content suite:
Royalty: Introduces the Empire faction and a noble title system. It adds psycasting (psychic powers), high-tech weaponry like mon swords, and new mechanoid threats.
Ideology: Focuses on social and belief systems. You can create custom religions or belief sets that dictate what your colonists find acceptable, such as cannibalism, slavery, or extreme nature worship.
Biotech: Widely considered the most transformative DLC, it adds children and reproduction, genetic engineering (xenotypes), and the ability to control your own mechanoid army.
Anomaly: A horror-themed expansion inspired by SCP-style lore. It includes eldritch monsters, containment mechanics, and "Deadlife" dust for reanimating corpses.
Odyssey: The latest exploration-themed expansion (released July 2025). It introduces Gravships for fast travel, new biomes, landmarks, and over 40 new animals. Gameplay Integration
Unlike separate game modes, all DLC content integrates directly into the base game simultaneously.
Replayability: Combining these allows for unique scenarios, such as a colony of genetically engineered vampire nobles following a blood-worshiping ideology.
Difficulty: DLCs like Anomaly and Royalty add powerful tools but also significantly increase the complexity of raids and external threats.

The sun didn’t rise over the colony of New Hope; it merely signaled its presence through the toxic fallout that choked the atmosphere of the rimworld.
Inside the mountain base, Kodiak, the colony’s lead researcher, adjusted his bionic eye. The hum of the Royalty psychic amplifier buzzed in his skull—a gift (and a curse) from the Empire for his service. Beside him, Val, a "hussar" soldier modified for peak combat, sharpened her plaststeel longsword. She didn't need to eat, but the Ideology of their "Steel-Worship" cult demanded she spend hours in the dark chapel, meditating before a slab of ancient machinery. "The shuttle is landing," Kodiak muttered.
Through the Biotech gestation vats, their newest "child"—a Highmate-gened laborer—was only days from waking. But there was no time for celebrations. An Anomaly had been detected in the nearby ruins: a flesh-beast that seemed to ignore standard physics, pulsing with a rhythmic, sickening light.
As the airlock hissed open, a group of Mechinator drones—small, clanking lifters and a heavy centipede—rolled out to meet the threat. They weren't just fighting for survival anymore; they were fighting to ascend. With the Anomaly monolith humming in the distance and the Empire's High Stellarch arriving for a visit, New Hope was no longer a simple farm. It was a nexus of gods, machines, and monsters. "Ready?" Val asked, her eyes glowing with a chemical fury.
Kodiak looked at the monitors—blood-red alerts flashing across the screens. "For this version of the rim? Always."
They stepped out into the gray snow, weapons drawn, ready to write another chapter in the blood-stained history of the Rim.
In the pantheon of modern PC gaming, few titles boast the replayability, depth, and emergent storytelling of Ludeon Studios’ RimWorld. For years, the game has been celebrated as a "story generator" that blends colony sim management with brutal survival elements. However, the experience changes dramatically when you move from the base game to the "Full" package. Specifically, the version identifier 143901 has become a hot topic within the community. But what is it? Why does it matter?
This article dives deep into everything you need to know about RimWorld 143901, why the "All DLCs Full" configuration represents the definitive way to play, and how this specific build harmonizes four major expansions: Royalty, Ideology, Biotech, and the newest arrival, Anomaly.
