State-gated storylets
Small events become available from location, items or relationships, then update state instead of duplicating whole branch trees.
The player's decision
Acquire a clue that opens another event or resolve the current relationship event?
Original scenario
Original: lamp oil plus knowing the keeper unlocks a night visit; a visited flag prevents repeating the first meeting.
Start with this prototype
Build six original events, three flags and one location. Define prerequisites, effects and repeatability; verify two reachable endings with developer state inspection and player recap.
Change one variable
Vary events per state to control choice density and repetition.
What to observe in a playtest
Enumerate reachable states for empty pools, duplicate rewards and unreachable endings.
Take the full design card
Includes rules, scope, tuning questions and sources for further planning. It does not create a project automatically.
