[[Immersive Sims (e.g., Deus Ex, Dishonored)]]
📌 Brief Summary
An immersive sim is a subgenre of action-adventure video games characterized by emergent gameplay, systemic complexity, and player agency. Rather than relying on scripted sequences, these games utilize interconnected "systems" (physics, AI, environmental interactions) to allow players to solve objectives through unscripted, creative methods that reflect their unique tactical choices.

📖 Core Content
The fundamental architecture of an immersive sim is built upon the principle of **Systemic Design**. Unlike traditional linear games where player actions trigger specific animations or scripted events, immersive sims utilize a "rule-based" environment. In this framework, objects and entities possess properties (e.g., flammable, conductive, heavy) that interact with global systems (e.g., fire, electricity, gravity). This creates **Emergent Gameplay**, where complex situations arise from the interaction of simple rules, often producing solutions or complications unintended by the original developers.

Key pillars of the genre include:
*   **Player Agency and Multimodal Problem-Solving:** The design philosophy prioritizes "verbs" over "paths." Players are presented with a goal (e.g., enter a locked room) and a toolkit of diverse methods (e.g., hacking a terminal, finding a vent, bribing a guard, or blowing up a wall). This ensures that the player's "playstyle"—stealth, combat, or social engineering—is an organic expression of their strategy rather than a forced progression.
*   **Environmental Storytelling and Cohesion:** Immersive sims rely heavily on "dense" level design. Information is conveyed through the placement of objects, audio logs, and architectural cues (the "lived-in" feel). This creates a sense of presence, where the world feels like a persistent, functioning ecosystem rather than a mere backdrop for combat.
*   **Consistent Internal Logic:** For emergence to function, the game's internal physics and AI must follow strict, predictable rules. If an explosion can break a wooden door, it must also be able to ignite a nearby cloth curtain. This consistency allows players to perform "systemic reasoning," predicting how the world will react to their interventions.

Historical lineage and evolution:
*   **Foundational Era:** The genre's roots are traced back to Looking Glass Studios' seminal works, such as *Ultima Underworld* and *System Shock*, which pioneered the integration of first-person perspective with complex RPG systems.
*   **The Golden Age/Refinement:** Warren Spector’s *Deus Ex* (2000) codified the genre by blending cyberpunk narrative with deep character customization and systemic choice. Later, Arkane Studios (*Dishonored*, *Prey*) refined these mechanics, focusing on high-fidelity environmental interaction and "verticality" in level design.
*   **Modern Iterations:** While the "pure" immersive sim has become a niche market due to high development costs, its DNA persists in modern "sandbox" titles and action-RPGs, influencing systemic elements in games like *The Legend of Zelda: Breath of the Wild*.

* Contradictions/Notes: There is an ongoing academic and critical debate regarding the definition of "Immersive Sim." Some scholars argue it is a design methodology (systems-driven) rather than a genre, while others focus on the psychological state of "presence" or "immersion" as the defining characteristic.
