| ==adventure games' formula==
| |
| * take a popular fiction game. E.g. a detective novel/
| |
| * create:
| |
| ** a background story
| |
| ** a map for the players to move around it
| |
| ** objects to manipulate
| |
| ** characters to interact with
| |
| ** '''a plot tree with several outcomes'''
| |
| * add: descriptions, dialogues, error messages and a vocabulary for the players
| |
|
| |
| ''game development then becomes much like planning and writing a piece of short fiction, except multiple outcomes must be conceived''.
