POE 2's 'Simulation Theory' League: Players Suspecting They're NPCs

[Annisa]

Blurring the Line Between Player and Code

In the speculative Simulation Theory League of path of exile 2 Items, the boundaries between players and non-player characters begin to dissolve. The core mechanic introduces environmental triggers, behavior mirroring, and dialogue trees so sophisticated that many players begin questioning whether they are being observed, manipulated, or even generated by the system itself. Unlike traditional leagues focused on loot or combat, this one challenges players' sense of agency by presenting the possibility that their actions are not entirely their own but instead scripted responses within a larger simulation.

Environmental Echoes and Pattern Recognition

One of the league's signature features involves zones that mirror the player’s past actions in eerily precise ways. For example, after performing a unique sequence of trades or skill casts, the next instance of a map may contain NPCs that mimic those same actions, almost like ghosts of the player’s past runs. These echoes expand over time and begin to predict the player’s movement or item use with unsettling accuracy. While the system is driven by complex procedural generation and data tracking, to the player it begins to feel as if the world is watching and scripting them in return.

Deconstructing Identity Through Dialogue Systems

NPCs in the Simulation Theory League respond to player input with language models that adapt over time. Rather than static questlines, these characters start to question the player’s motivations and even suggest that they themselves might be playing a role assigned by unseen forces. As players engage in repeated conversations, the dialogue deepens into philosophical reflections on choice, purpose, and artificiality. Some NPCs will ask questions like “When was the last time you chose something that wasn’t offered?” or “Do you remember your first act, or did you simply begin?” These moments cause players to reconsider whether their character’s actions are driven by them or by the game’s hidden architecture.

Algorithmic Interference in Gameplay Decisions

In this league, trading and skill tree customization are occasionally “interfered with” by unseen forces. A mysterious modifier known only as the Paradox Effect sometimes overrides a player’s decision, subtly nudging them toward alternate builds or market choices. While initially jarring, these moments are integrated into the game’s lore as signs of a greater codebase observing the simulation and occasionally injecting anomalies. Over time, players begin to interpret these events as messages rather than bugs, feeding into the growing sense that their presence is both fabricated and purposeful within the system.

The Psychological Toll of Synthetic Reality

As the league progresses, many players report experiencing a creeping sense of existential dislocation. Mechanics such as time loops, recursive zone designs, and impossible coincidences reinforce the illusion that the player character may be nothing more than a highly responsive NPC in someone else’s simulation. This shift is amplified by social features in which player-controlled characters mimic each other’s behaviors in real time, leading to confusion over who is a human and who is algorithmically generated. The Simulation Theory League thus becomes a mirror not just for the game world but for the players themselves, forcing them to question the origin of their actions and the authenticity of their control.

Designing a Game to Question Its Players

By building a game system that reflects and refracts player behavior back at them, POE 2 engineers a unique psychological experience. The Simulation Theory League invites players to treat the game as more than a source of entertainment and instead as a lens for self-examination. Through uncanny imitation, subtle manipulation, and philosophical confrontation, the league transforms each moment of gameplay into a meditation on what it means to choose, to act, and ultimately, to be real within a digital space that questions everything—including the player’s role in it.
