What the estimate includes
The 8–10 hour figure comes from the developer's own Steam description and refers to the main story. It is an estimate, not an independently measured average from finished players.
With 32 main missions, the headline estimate implies a fairly focused pace. Time spent attending classes, exploring, shopping, or completing all 15 side activities can extend a playthrough.
Completionist time is not known yet
No verified completionist time is available before release. Achievement requirements and collectible counts are also not published through the Steam store data yet.
This guide will add measured story, story-plus-extras, and full-completion ranges after multiple play reports exist instead of turning a single speedrun into an average.
Plan for two runs only if choices matter enough
Two endings create a reason to revisit the prom decision, but the game has not confirmed whether they require a complete second playthrough. Keep a late-game save if the save system permits it.
A first run should prioritize the story and systems you enjoy rather than trying to follow an unverified perfect schedule.
Current verified number: 8–10 hours for the main story. Longer estimates are pending real play data.
