"I don't write stories; I build systems that create stories." With that defining mantra, the RimWorld director unpacked the philosophy behind his work and the genesis of the 'Ideology' DLC.

On the second day of NEXUS Co., Ltd. Developers Conference 2026 (NDC26), held on the 17th at the Gyeonggi Content Agency's international conference hall, a session titled 'What the System I Build is Saying - Questions Posed by RimWorld Ideology' took place. The stage featured Tynan Sylvester, director of Ludeon Studios, alongside moderator Lee Kyeong-hyeok, editor-in-chief of Game Generation. The pair delved into the director’s unique system design philosophy and the profound insights into human society embedded within the 'Ideology' expansion.

The conversation kicked off with that familiar question: is the man who builds story engines actually a writer? Tynan replied, "If I had to pick one word, I'd say 'System Crafter.' It's a semantic distinction. I'm not just writing a narrative; I'm building systems that generate stories through recurring event patterns. These systems create subsets of possibilities that respond to player actions, resulting in a unique tale every time."

Tynan’s perspective is rooted in the sheer breadth of choice games provide. "Games have a 100-fold wider scope than any traditional medium," he noted. "There’s so much you can do—single-player, multiplayer, competitive, cooperative. You can weave stories, engage in art, or even commerce." He emphasized that games are a completely new medium, unearthing values and genres that didn't exist even 30 or 40 years ago.

The heart of the discussion was 'Ideology,' the expansion that fundamentally evolved RimWorld’s identity. In the vanilla game, hardcoded systems applied universal penalties to extreme acts like cannibalism or organ harvesting. Tynan realized this design fell into the trap of defining absolute cosmic morality. To model the reality that people hold vastly different values, he created 'Ideology.'

With 'Ideology,' RimWorld moved beyond 'describing facts' to becoming a neutral universe that makes no 'claims of social necessity.' Within this framework, societal systems—or beliefs—dictate reality; what is a horrific crime to one group becomes a sacred, righteous act for another.

Tynan explained, "Ideology models the fact that everyone’s values differ. It’s easy to forget that in reality, but understanding that people simply want different things in the universe is crucial. Some disagreements are about how to reach a result, but mostly, people just want different things. We can debate whether cannibalism is 'right,' but much of it simply boils down to preference." He successfully baked the concept that morality and ethics are relative constructs into the game's mechanics.

Addressing the community’s dark memes—calling the game a 'war crime simulator' or a 'Geneva Convention checklist'—Tynan offered a surprisingly upbeat analysis. "I don't think this 'war crime simulator' approach is how most players play long-term," he said. "They try it for the novelty, share a laugh with friends about their 'eight-wife slave colony,' and then go back to playing normally." He noted that players eventually gravitate toward finding ways to make society function.

In this 'safe space without a nanny,' players experiment with taboos, deriving a unique emotional thrill. Sharing these antisocial exploits is essentially a form of high-level social bonding—a way of trusting friends enough to reveal one's own 'inner fragment of evil.' These 'accidental operations' from such deviance even help inform the 'intentional operations' of the game's design.

Tynan’s fundamental faith in human nature was the session's highlight. He pointed to statistical evidence showing that despite players dabbling in dark, criminal play, they eventually return to building stable, cooperative communities that prioritize safety and comfort. RimWorld’s systems are balanced so that trust and cooperation are far more effective for long-term survival than mindless violence—a mirror of the reality we live in.

When asked if he 'loves humans,' Tynan replied, "I think humans are the most terrifying, fascinating, powerful, and lovable beings in the universe. I love them precisely because they are so complex—because it is who we are. I’m not particularly interested in rocks floating in space."

He added, "Of course, there is much darkness and violence within us, and I think that’s necessary. It’s part of the means by which we’ve evolved to this point. We must observe and integrate these multifaceted aspects. You don't necessarily have to love or hate someone; love and hate are things that fluctuate depending on the era and the situation."

On the hot topic of AI and machine learning, Tynan was pragmatic. "It’s not a major issue in game development," he stated. "People use AI to generate code, but if you aren't competent, you won't be able to review that code, the quality will drop, and you’ll inevitably face problems later." He drew a hard line: "I don't believe using AI changes a game’s message or creates a massive difference in content. It’s purely a matter of quality."

He also touched on the 'Anomaly' expansion and the game's 'Archotech' super-intelligences. He compared humans in such a world to an 'anthill next to an office building,' explaining that super-intelligences can coexist with humans precisely because they have zero interest in us. While powerful for storytelling, these omnipotent entities are too grand to care about controlling human behavior.

As the session drew to a close, Tynan offered advice to aspiring 'System Crafters' in Korea. "Don't just rely on intuition or things that look pretty in your head. You need a solid theoretical framework to analyze why your mechanics trigger specific emotional responses," he urged. "Be flexible—create cheap prototypes in a 'grey box' state without graphics, iterate constantly, and focus on analyzing why you want to make what you're making." With that, he wished them the best of luck in their journey to build great games.
