The developers estimate 15+ hours for the main story, with total time varying by playstyle. Branching choices, optional orders, repair pace, competitions, and achievement cleanup can extend a save well beyond that baseline. The pre-release FAQ says players can spend 15+ hours on the main story and continue as long as they like. It also names branching storylines, device customization, and online orders as replayability factors. Treat 15+ as an official estimate, not a speedrun promise or completionist average.
Official answer: 15+ hours for the main story
The pre-release FAQ says players can spend 15+ hours on the main story and continue as long as they like. It also names branching storylines, device customization, and online orders as replayability factors. Treat 15+ as an official estimate, not a speedrun promise or completionist average.

Orders begin at the counter. Read the request, then check the To-Do list before deciding that progress is blocked.
What changes your total time
Careful teardown and reassembly take longer than familiar repeat repairs. Reading every dialogue branch, accepting extra email work, practicing competitions, rebuilding shop cash, and protecting multiple choice saves all add time. Reusing a verified checkpoint is faster than replaying a whole route after an exclusive invitation.
Story versus 100 percent
Finishing the narrative is not the same as unlocking all 50 achievements. Day-based goals, route-exclusive achievements, every-device competition wins, licenses, and shop milestones belong to a longer completion plan. Keep the first playthrough spoiler-light, then use named saves for focused cleanup.

Story progress can depend on a completed repair, a To-Do, and the next conversation. Check all three before treating a quiet shop as a softlock.
A low-stress route
Learn the repair loop, keep two rotating saves, finish visible story tasks before taking a large optional queue, and preserve checkpoints before major hand-ins. After the credits, compare missing achievements and routes instead of starting over blindly.
