In inZOI, the trait system is built approximately on the Enneagram personality model.
Each Zoi’s personality is shaped by roughly one of the nine Enneagram types, combined with two “wings” (sub‑types) for added nuance. This creates a total of 18 distinct personality traits in the game, each with its own strengths, weaknesses, and behavioral tendencies.

Weaknesses of inZOI’s Enneagram‑Based Trait System
- Minimal gameplay impact — personality type and wings have little to no visible effect on behavior; Zois with different types often act identically.
- No dynamic personality growth — once chosen, a type stays static; there’s no organic shift in traits based on life events or player choices.
- Wish pattern locked to trait — short‑term wishes on the panel are heavily influenced by the main trait, which can make different Zois feel repetitive if they share the same type.
- Lack of synergy with AI — the neural network‑driven AI doesn’t leverage personality data to create unique routines or decision‑making patterns.
In this regard, I propose basing the traits on an underlying system of personality parameters and skills.

Game Systems:
-
In Disco Elysium, there are 4 core attributes, they are expressed through emotional and cognitive aspects.
-
In The Sims 2, there are 5 personality scales (Neat, Outgoing, Active, Playful, Nice).
-
In The Alters, there are 9 Personality Skills (Assertiveness, Charisma, Chill, Integrity, Joy of Life, New Perspective, Optimism, Pragmatism, Vulnerability, Shrewdness, and Reliance).
Personality Psychology:
- In HEXACO, there are 6 factors, including Honesty–Humility.
- In the Big Five model, there are 5 factors: OCEAN (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) — the first model used in inZOI.
In our current framework, most types can be described through 6 key motivational vectors.
Mapping Parameters to Big Five, HEXACO, Enneagram, MBTI
| Parameter | Big Five (OCEAN) | HEXACO | Skills (Enneagram) |
|---|---|---|---|
| Empathy | Agreeableness | Emotionality / Agreeableness | Friendliness, Compassion, Sensitivity (Types 2, 9) |
| Ambition | Conscientiousness / Extraversion | Conscientiousness / Extraversion | Activity, Diligence (Achievement‑striving), Recognition (Types 3, 1) |
| Curiosity | Openness to Experience | Openness to Experience | Exploration, Novelty, Creativity (Types 5, 7) |
| Control | (inverse of) Neuroticism / Conscientiousness | (inverse of) Emotionality / Conscientiousness | Authority, Order, Security (Types 8, 6) |
| Individualism | Openness to Experience | Openness to Experience | Uniqueness, Authenticity, Self-expression (Types 4, 5) |
| Stability | (inverse of) Neuroticism | (inverse of) Emotionality | Safety, Predictability, Comfort (Types 6, 9) |
| (UPD) Integrity | - | Honesty–Humility | Ethics, Sincerity, Modesty (Types 1, 2, 9) |
Starting Points
At the beginning of the game, you receive a pool of 18 (UPD 21) points to distribute across the six core parameters: Empathy, Ambition, Curiosity, Control, Individualism, Stability, UPD Integrity
- Minimum per parameter: 1 point
- Soft cap at creation: 8 points
- Absolute maximum: 10 points (can only be reached later through progression)
Your initial allocation will define your character’s early strengths, weaknesses, and available interactions. Even if a parameter starts low, you can still unlock related skills later — but it will cost more experience and progress will be slower compared to starting with a higher value.
Let’s break down example parameter distribution (18 points total)
Type A:
| Parameter (Points) | Skillpoints |
|---|---|
| Empathy (2) | Friendliness (1) Compassion (1) Sensitivity (0) |
| Ambition (5) | Activity (2) Diligence (2) Recognition (1) |
| Curiosity (2) | Exploration (1) Novelty (1) Creativity (0) |
| Control (1) | Authority (1) Order (0) Security (0) |
| Individualism (6) | Uniqueness (2) Authenticity (2) Self‑expression (2) |
| Stability (2) | Safety (1) Predictability (1) Comfort (0) |
| Integrity (3) | Ethics (3), Sincerity (0), Modesty (0) |
Motivational Profile Analysis
- High Individualism (6) + High Ambition (5) → strong drive for self‑expression, achievement, and recognition.
- Low Control (1) + Low Stability (2) → thrives in unpredictable environments, not seeking rigid structure.
- Moderate Empathy (2) + Curiosity (2) → approachable and open‑minded, but not overly sentimental or probing.
Likely Enneagram Type: 4w3
- Type 4 — Individualist: seeks uniqueness, fears being “nobody.”
- Wing 3: adds ambition, competitiveness, and desire for visibility.
Matching inZOI Main Trait: Individualist (5.2)
- Represents emotional depth, authenticity, and a strong need for personal expression.
Recommended inZOI Sub‑Traits:
| Sub-Trait | Enneagram | Fit |
|---|---|---|
| Adventurer (7.1) | 7w8 — thrill-seeking, assertive |  Fits due to low Control/Stability |
| Entertainer (7.2) | 3w2 — performative, engaging | May clash with Integrity 3 — Entertainer leans toward charm over principle |
| Go-Getter (4.2) | 3w4 — ambitious, emotionally aware | Better match now — ambition + emotional depth + ethical nuance |
| Dreamer (1.2) | 4w5 — introspective, imaginative |  Optional — if player wants to lean into authenticity over performance |
Type B:
| Parameter (Points) | Skillpoints |
|---|---|
| Empathy (6) | Friendliness (2) Compassion (2) Sensitivity (2) |
| Ambition (1) | Activity (0) Diligence (1) Recognition (0) |
| Curiosity (3) | Exploration (1) Novelty (1) Creativity (1) |
| Control (1) | Authority (1) Order (0) Security (0) |
| Individualism (3) | Uniqueness (1) Authenticity (1) Self‑expression (1) |
| Stability (4) | Safety (2) Predictability (1) Comfort (1) |
| Integrity (3) | Ethics (1), Sincerity (2), Modesty (0) |
Motivational Profile Analysis
- High Empathy (6) → This Zoi is deeply attuned to others’ emotions, likely to be nurturing, diplomatic, and emotionally intelligent.
- High Integrity (5) → Strong moral compass, principled, sincere, and modest; likely to act ethically even under pressure.
- Low Ambition (1) → Not driven by external validation or success metrics; may avoid competitive environments.
- Low Control (1) → Prefers freedom over structure; unlikely to impose rules or seek authority.
Likely Enneagram Type: 9w1: The Mediator
- Type 9: peaceful, conflict-averse, seeks inner and outer harmony.
- Wing 3: adds idealism, moral clarity, and a quiet sense of purpose.
Matching inZOI Main Trait: Mediator (1.1)
- Represents serenity, empathy, and a desire to maintain balance.
- Likely to thrive in social roles, caregiving professions, or community-building gameplay.
Recommended inZOI Sub‑Traits:
| Sub-Trait | Enneagram | Fit |
|---|---|---|
| Collaborator (8.1) | 6w7 — loyal, team-oriented | Matches empathy, stability, and low ambition |
| Dreamer (1.2) | 4w5 — introspective, imaginative | Supports curiosity and inner harmony |
| Volunteer (3.1) | 2w1 — caring, morally focused | Optional — fits empathy + integrity, but may feel too externally driven for low ambition |
Skillpoints Progression
As the game progresses, certain skills can be gained or improved through gameplay. Completing activities, pursuing careers, building relationships, and achieving milestones can all grant additional points to your core parameters or unlock new skill levels. This allows your Zoi’s personality and abilities to evolve beyond the initial setup.
This means your Zoi can grow from the initial 18 (21) total points to a theoretical maximum of 60 points if every parameter reaches its cap — allowing their personality and abilities to expand far beyond the starting setup.
Example of how empathy can be increased or decreased.

Optional — fits Curiosity, but may lack ambition |
Summary
A distinctive Zoi with strong individuality and ambition, designed to stand out. Over time, they can expand their skills and adapt their personality through in‑game progression.
I really wish the topic of personalities in inZOI were raised more often and more willingly, because it’s the game’s core problem and so underrated… probably too complex to express clearly. The developers simply have no input from players on how they’d want these systems to work. Now I truly hope that temperaments and mood won’t just be an isolated add-on, but fully interdependent systems.
