Life simulation players can speed up the clock rather than watch a character sleep. For inZOI's experimental Smart Zoi feature, that familiar control affected what the system could do. Krafton's March 2025 guide said the feature temporarily disabled creating journal entries and editing schedules while playback ran at five times normal speed or faster.
The guide also warned that new schedule entries could fail when a Zoi went to bed late, and that inner thoughts could disappear quickly during conversations. It described Smart Zoi as an opt-in experiment with high hardware requirements and an English-only text prompt at that stage.
Those are launch-era observations, not a list of current limitations. They give a concrete example of where generated character behavior meets rules players already rely on, including the ability to change how quickly the rest of the world moves.
