NPC dialogue writer with branching choices

The prompt

Write a branching dialogue tree for {{npc_name}}, a {{personality_trait}} character in a {{game_genre}} game. Include 3 player response options at each branch, each leading to a distinct NPC reaction.

Expected result

A dialogue tree with the NPC opening line, three player choices, and a distinct NPC reaction branch for each choice.

Why it works

Specifying "3 player response options at each branch" keeps the tree a fixed, implementable size instead of an unbounded, hard-to-wire conversation graph.
