Dialogue tree

Dialogue tree allows to elicit responses from non-player characters by choosing an option from a pre-written list of sentences or keywords. The dialogues may also be branching, allowing the player to continue the interaction by choosing subsequent dialogue options or choosing the same option another time to repeat a specific part of the conversation. The mechanic is common in genres such as adventure or RPG. In some cases, such as multiple western RPG and narrative adventure games, choosing particular dialogue options may carry consequences affecting the narrative.
