Celia Hodent
French UX consultant and psychologist. Holds a PhD in psychology; led user experience for Ubisoft and LucasArts before becoming VP of User Experience at Epic Games, where she built the UX practice behind Fortnite’s rise. Now an independent consultant. Author of The Gamer’s Brain (2017).
Why she matters here
Hodent is the wiki’s first source to treat game UX as a discipline built from cognitive-science fundamentals rather than from marketing or growth practice. Her central contribution is a two-part definition — Game UX = Usability + “Engage-ability” — that reframes most of the wiki’s existing persuasion/monetization material as one half (engage-ability) of a larger discipline that also includes ease-of-use:
- Game usability — her Seven Pillars, adapting Nielsen’s usability heuristics to games.
- Game engage-ability — her Three Pillars (Motivation, Emotion, Game Flow), her own coined term and the more game-specific half of the framework.
- She is also the source of this wiki’s clearest single critique of surface-level gamification (see PBL fallacy) and its first sustained warning about the Overjustification effect as a design risk in daily-login and streak mechanics.
Her citation habit varies sharply by topic: Part I of her book (the cognitive-science primer) cites academic literature almost paragraph-by-paragraph; Part II (her own Game UX framework) leans much more on her own Ubisoft/LucasArts/Epic practitioner experience, citing frameworks like Self-Determination Theory and GameFlow (Flow (psychology)) as building blocks rather than deriving her Pillars from a single external source.
Key facts
- PhD in psychology; professional background spans Ubisoft, LucasArts, and Epic Games (Fortnite).
- Coined the term “engage-ability” to name the fun/motivation/immersion half of game UX, distinguishing it from usability (which she treats as the necessary-but-insufficient half).
- Runs a companion site and consultancy at thegamersbrain.com.
