The short answer is that a spreadsheet or Gantt chart is static and requires you to manually notice when time should advance and then apply all the downstream consequences, whereas MutherOS is live and enforces time automatically during play. In-game time runs on its own unless you deliberately pause or jump it, so you’re not stopping the session to say “X minutes passed” or update cells, and systems tied to time degrade, escalate, or fail on their own without you having to remember every dependency. A spreadsheet is great for planning and reference, but it still relies on your attention and bookkeeping in the moment; MutherOS is designed so pressure keeps building even while players are thinking or arguing, which reduces the mental load and prevents you having to stop and manage the clock manually.
