In the ever-evolving landscape of video games, role-playing games (RPGs) have long stood out for their ability to immerse players in rich, interactive worlds. At Mind Mage, we've been exploring how to take this immersion to the next level by leveraging AI to create agentic storytellers. But what makes these experiences engaging? Enter the concept of Player Experience of Needs Satisfaction (PENS).
PENS is a framework that helps us understand why certain games resonate so deeply with players. It focuses on three core psychological needs: Autonomy, Relatedness, and Competence. Today, we're going to dive into how agentic storytellers can enhance these aspects of player satisfaction in ways that traditional computer RPGs simply can't match.
Understanding PENS
Before we delve into the specifics, let's briefly explore what PENS is all about. Developed by Scott Rigby, Richard Ryan, and Andrew Przyblski, PENS is rooted in Self-Determination Theory, a broad framework for understanding human motivation. In the context of gaming, PENS suggests that players are most engaged and satisfied when a game fulfils these three basic psychological needs:
- Autonomy: The feeling of having meaningful choices and control over one's actions. Elder Scrolls: Skyrim tracked many of your choices through numerous reputation systems with different factions. Choices that favour one faction can impact how others treat you.
- Relatedness: The sense of connection with others and feeling that one matters in the game world. Mass Effect even managed to carry this over between games by having your squad mates return to help you.
- Competence: The experience of growth, achievement, and mastery within the game. Portal is a great example where puzzles gradually become more complex but the player feels they have a broader set of tools to solve those puzzles.
Understanding and catering to these needs is crucial for creating captivating gaming experiences. Now, let's explore how agentic storytellers can take each of these elements to new heights.

Autonomy: Breaking Free from Predefined Paths
In traditional computer RPGs, player autonomy is inherently limited by what the game developers have pre-programmed. No matter how vast the world or how many dialogue options are available, players are ultimately constrained by a finite set of choices and outcomes.
Agentic storytellers, on the other hand, can offer a level of autonomy that's simply not possible in conventional games. As we discussed in our previous post on "Open Narrative Gaming," these AI-driven storytellers can understand and respond to player actions that weren't explicitly anticipated by game designers.
Imagine wanting to persuade a town's mayor that their political rival is in league with your nemesis. In a traditional RPG, this kind of complex, player-initiated plot development would likely be impossible unless specifically written into the game. With a storyteller, however, players can attempt any action they can imagine, and the AI can evaluate its plausibility and consequences in real-time.
This dynamic responsiveness extends to the entire game world. Where traditional RPGs might offer a handful of solutions to a given problem, a storyteller can adapt to virtually any approach a player might conceive. Want to use that fire extinguisher as an impromptu jet ski? In a world guided by an AI storyteller, your creativity is the only limit.
The result is a game that truly feels like a tabletop RPG session with an infinitely patient, infinitely creative game master. Players are free to shape the story in ways that feel natural and personal, rather than being funneled down pre-determined paths.
Relatedness: From Scripted NPCs to Living, Breathing Characters
Relatedness in gaming is about more than just multiplayer interactions. It's about feeling connected to the game world and its inhabitants. Traditional RPGs have made great strides in this area, with complex dialogue trees and character relationship systems. However, these interactions are ultimately limited by their scripted nature.
Storytellers can take relatedness to a whole new level. Instead of interacting with pre-written NPCs, players can engage with dynamically generated characters that evolve based on their interactions. The AI storyteller can create personalities on the fly, complete with their own motivations, quirks, and emotional responses.
This dynamic character generation allows for much more nuanced and meaningful relationships. NPCs can remember past interactions, form genuine opinions of the player based on their actions, and react in ways that feel personal. The storyteller can even adjust the personality traits of key characters to better resonate with individual players, creating a cast that feels tailor-made for each person's journey.
Moreover, the AI storyteller itself can serve as a source of relatedness. Like a human game master, it can offer encouragement, challenge players in personalized ways, and even inject humor or drama as appropriate. This creates a sense of having a responsive, intelligent guide through the game world, enhancing the feeling of connection and importance within the narrative.
Competence: From Generic Quests to Personalized Triumphs
Competence, or the sense of growth and mastery, is a crucial element of player satisfaction in RPGs. Traditional games typically rely on levelling systems, skill trees, and pre-designed quests to provide this sense of progression and achievement.
Agentic storytellers can take this to the next level by offering personalized challenges and growth opportunities. Instead of generic quests that every player experiences, the AI can craft challenges that are uniquely suited to each player's skills, preferences, and narrative choices.
For example, if a player has shown a preference for diplomatic solutions, the storyteller might present them with increasingly complex negotiation scenarios. If they've been focusing on stealth, it might generate a series of infiltration challenges that grow progressively more difficult. This adaptive approach ensures that players always feel like they're being meaningfully challenged and growing in ways that matter to them.
The storyteller can also provide a more nuanced and personalized sense of character progression. Rather than relying solely on numerical stat increases, it can narrate subtle improvements in a character's abilities based on their experiences. A player who frequently engages in persuasive dialogue might find their character becoming more charismatic over time, even without explicitly investing in a "charisma" stat.
Perhaps most importantly, agentic storytellers can provide a sense of mastery that goes beyond simply seeing the end credits. By understanding a player's motivations and the choices they've made throughout the game, the AI can craft concluding scenarios that feel like the natural culmination of their unique journey. This personalized resolution can provide a sense of competence and accomplishment that's hard to achieve with pre-written endings.
The Synergy of Autonomy, Relatedness, and Competence
While each of these elements is powerful on its own, the true magic happens when they work in concert. Agentic storytellers can create a feedback loop where increased autonomy leads to more meaningful relationships, which in turn provide more satisfying opportunities for developing competence.
For instance, a player's autonomous decision to help a seemingly minor NPC might lead to that character becoming a key ally later in the story. The deepening relationship with this NPC could then open up new challenges and opportunities for growth that wouldn't have been available otherwise. This interconnected web of choices, relationships, and achievements creates a richly satisfying player experience that feels uniquely personal.
Looking Ahead: Challenges and Future Possibilities
Of course, implementing agentic storytellers comes with its own set of challenges. Balancing player freedom with narrative coherence, ensuring consistent character behaviour, and managing the technical complexities of real-time story generation are just a few of the hurdles we're working to overcome.
Moreover, as AI becomes more central to gameplay experiences, we'll need to grapple with important ethical considerations. How do we ensure fairness and avoid biases in AI-generated content? How do we maintain player privacy while creating personalized experiences?
These are fascinating questions that deserve deep exploration. In future posts, we'll dive into these challenges and discuss the cutting-edge technologies that are making AI storytellers possible.
Conclusion: A New Frontier in RPG Experiences
Agentic storytellers represent a quantum leap forward in our ability to satisfy players' needs for autonomy, relatedness, and completion in RPGs. By breaking free from the constraints of pre-programmed choices, creating dynamic characters and relationships, and offering personalized paths to growth and achievement, these AI-driven experiences can offer a level of engagement and satisfaction that traditional computer RPGs can only dream of.
As we continue to develop this technology at Mind Mage, we're excited about the possibilities it opens up. Imagine RPGs where every playthrough is a unique story, where characters feel as real and unpredictable as those in the best novels, and where your growth as a player is reflected in subtle, meaningful ways throughout the game world.
