Triangle of identities
- 'There are at least three identities involved in play: the person typing and reading ("player"), the main character within the story ("protagonist"), and the voice speaking about what this character sees and feels ("narrator"). There is a triangle of relationships between them, and it's a triangle with very different proportions in different games.'
- — Graham Nelson, The Inform Designer's Manual, Fourth Edition, p.368
There is some discussion of the 'different proportions' in the glossary entries linked above, and a more detailed exploration in Nelson's article.
The following games subvert the triangle of identities or present it in unusual ways:
- Bellclap (Tommy Herbert; 2004; Z-code).
- Fail-Safe (Jon Ingold; 2000; Z-code 5).
- LASH (Paul O'Brian; 2000; Z-code 8).
- The Milk of Paradise (Josh Graboff; 2009; Z-code).
- Pantomime (Robb Sherwin; 2006; Hugo 3.1).
