Real-Time Persistence

Living Universe Online runs on real-world time, continuously, whether or not you are playing.

What This Means

Everything in the game that takes time — constructing a building, moving a fleet, processing a trade order, executing a research project — counts down in real-world hours and minutes. If a fleet takes four hours to reach its destination, four real-world hours must pass before it arrives. If a construction project takes twelve hours, it will be ready in twelve hours, whether you close the game after clicking the button or not.

The game does not pause, accelerate, or stop when you log out. Other players continue playing. Fleets continue moving. Projects continue progressing. The galaxy keeps turning.

Why the Game Works This Way

This design puts strategy and planning at the center of the game, not reaction speed or the number of hours you can sit in front of a screen.

A player who plans well — who queues the right projects, dispatches fleets at the right moment, and sets up logistics before they are needed — will be effective even with limited play sessions. A player who spends all day clicking will not automatically outperform a player who spends thirty minutes thinking.

The real-world clock is a shared resource. It creates genuine tension: a fleet mid-route is a commitment, not a hypothetical. A building under construction cannot be instantly cancelled and restarted. Choices have weight because time cannot be reclaimed.

What It Affects

Real-world time governs every activity in the game, including:

  • Fleet movement — all travel between stellar objects, across systems, and between regions takes real time based on distance and route properties.
  • Construction — building infrastructure, facilities, and defenses on a stellar object takes real time based on the project and available resources.
  • Research and development — advancing technology or unlocking new capabilities takes real time.
  • Trade and logistics — shipments, contracts, and supply chains operate on real schedules.
  • Production — extracting resources, manufacturing goods, and generating output all happen continuously at a rate proportional to elapsed time.

Nothing resolves instantly. Nothing skips the clock.

Notifications and Absence

Because the game runs without you, the notification system is how you stay informed. When a fleet arrives, a project completes, or something unexpected happens, you receive a notification you can review at any time.

You do not need to be watching the game for things to happen. You need to be ready to make the next decision when you return.

What It Does Not Mean

Real-time persistence does not mean the game punishes absence.

A player who logs off for a week returns to a galaxy that has moved on — but their own holdings, fleets, and infrastructure continue on the trajectory they set. A well-managed empire does not fall apart overnight simply because its player was away.

The specifics of how absence affects different game systems — defence, production, diplomacy — are defined in the relevant feature pages.
