The Elder Scrolls V: Skyrim
- Dialogue example:
  - “I have been watching you, Dovahkiin. You are a strange and wondrous thing, full of sorrow and purpose. A warrior of the ancient times, reborn into a world that has no need for your kind.”
  - “I have a task for you, if you are willing. A quest, you might say. To clear the skies of these damned dragons, once and for all.”
The Last of Us
– “I don’t want to die, Ellie. I don’t want to be the one who’s dead when you look at me.”
– “I don’t know how much more of this I can take, man. The people we lost… They didn’t just die. They were killed by the very same assholes who think they can just waltz in and take what they want.”

2. Literature

Ender’s Game by Orson Scott Card
– “You know, when I was your age, I was real ugly. Ugly and smart, and I got the two mixed up for a long time.”
– “It’s not just that they’re afraid of you, it’s that they don’t like you, and they never will. They’ll never accept you, and they’ll never like you.”
To Kill a Mockingbird by Harper Lee
– “It’s a lot harder to be a good person than it is to be a bad person.”
– “Mockingbirds don’t eat much, but boy, when they do, they have a long, lingering spree; that’s why it’s a sin to kill a mockingbird.”

Creating Memorable NPCs

Developing a unique personality

Creating memorable NPCs is a crucial aspect of interactive storytelling, as these characters often serve as the primary source of player interaction and influence the direction of the story. To develop a unique personality for an NPC, there are several key elements to consider:

Background and history: The NPC’s backstory and history can greatly influence their personality and motivations. This information can include their upbringing, life experiences, and relationships with other characters.
Physical appearance and mannerisms: An NPC’s physical appearance and mannerisms can also play a role in their personality. For example, a character with a gruff exterior may be hiding a kind heart, while a character with a soft voice may be fiercely independent.
Dialogue and speech patterns: The way an NPC speaks and interacts with the player can also shape their personality. This includes not only the words they use, but also their tone, pace, and inflection.
Beliefs and values: An NPC’s beliefs and values can greatly influence their actions and interactions with the player. These can be shaped by their upbringing, life experiences, and cultural background.
Goals and motivations: Every NPC should have goals and motivations that drive their actions and decisions. These can be personal, such as a desire for power or revenge, or they can be tied to the larger story and plot.

By considering these elements and carefully crafting an NPC’s personality, developers can create characters that feel realistic and relatable to players, and that drive the story forward in unexpected and engaging ways.

Incorporating character arcs and growth

One of the most effective ways to create memorable NPCs in interactive storytelling is by incorporating character arcs and growth. A character arc is the journey that a character takes throughout the story, and it is essential to make the NPC’s journey as compelling as the main character’s.
