Do you need a goal the game can resolve?
A conversation can succeed by being coherent and interesting. A game often needs a more explicit endpoint: find the object, identify the source or reach a place under a constraint. The extra state is useful when it represents progress toward that endpoint.
LusyChat’s FAQ documents character descriptions, initial scenarios and greetings. Rochat’s AI AVG guide documents scenes, task objectives, player settings and numeric success/failure conditions. The distinction is authoring control, not evidence that one product writes more convincing dialogue.
Design a small mystery before a large world
An original neutral scenario can ask an adult curator to identify which of three catalogue records belongs to a painting. In open character chat, discussion can move the story forward without an explicit counter. In an objective-driven game, the author should decide what counts as evidence and what resolves the identification.
A score should have a cause. Repeating an already known clue should not necessarily count as discovering a new one. The final scene should correspond to the objective rather than declaring success simply because enough turns have passed.
Rochat’s guide calls for integer values, exactly one success value and at least one failure value. It also warns that unexpected value changes can indicate insufficiently clear rules. These are useful authoring constraints; they do not turn an AI narrative into a deterministic program.
| If the scene needs… | Start by defining… |
|---|---|
| A recognizable personality | Behavior and motivation |
| A clear relationship | Who each participant is |
| An open conversation | The current situation and unresolved decision |
| A measurable ending | Objective, state changes and end conditions |
More rules create more things to test
An instruction can conflict with another instruction. A game can reach a success threshold while its narrative still describes an unresolved problem. Plan a small manual playthrough that includes success, failure and an unexpected user choice before expanding the world.
For an ordinary character exchange, simpler setup may be preferable. LusyChat’s recent-context explanation also argues for keeping the active scene clear rather than burying it under an enormous biography. Rochat’s Character Info guide likewise emphasizes behavior and reactions, with documented character/player variables.
Choose game authoring when defining state and outcomes is part of your creative goal. Choose an open character scene when the next conversation is the goal itself. No game execution or character-memory benchmark was performed here.
