LOOP/CYCLE STRUCTURE
The game's world resets on a repeating cycle — a time loop the player relives, a day that restarts, a cataclysm that recurs — with knowledge (and sometimes select resources) persisting across iterations.

Outer Wilds is the masterpiece: a 22-minute solar system loop where the only progression is what you've learned; Majora's Mask runs a three-day cycle with scheduled NPC lives to memorize and manipulate; Deathloop and Twelve Minutes structure thrillers around it; and roguelike runs are the loose genre-wide cousin. Designers use loops because they let knowledge replace power as the progression currency — the world can stay dense and hand-crafted because the player traverses it many times with compounding understanding, and failure converts from setback into research. Loops also enable clockwork worlds: NPCs on schedules, events at fixed times, and the distinct mastery pleasure of being everywhere on time. Key decisions: loop length (long enough to act, short enough that resets don't grieve), what persists (knowledge only is purest; items and unlocks soften the concept toward convenience), and whether the loop is diegetic — characters aware of it become co-conspirators, unaware ones become tragedy. Pitfall: repetition without compression — if known-solved segments can't be skipped, fast-traveled, or shortcut by mastery, later loops spend most of their runtime re-performing homework, and the structure's core promise (every loop spent on the frontier of your understanding) collapses into commute.
