==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'''
[[File:game-map.svg|thumb|Plot tree]]
* 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''.
Aarseth, Espen J. 1997 ''Cybertext''
==the city==
Can we create a web-based game, that can played within the physical space of the city, using mobile phones?
The city game can become a way of exploring a space, a city, an excuse to drift (dérive), experience and perceive the city differently from our day-to-day understanding of it.
== choose you own adventure in the city==

A very simple example using JS and jQuery

===discussion===
How is this game constructed?
*  '''scenes'''; Each scene contains:
** number. E.g. <code>scene_2</code>
** title
** msg
** img (option),
** question
**  connect(ing scenes)
* html template (empty tags) that are replace as the game progresses
What can be changed in this game?
=== assignment===
Design a new game, that has to although existing in the Internet, has to interfere with real-life.
It has to interfere with the real world, the physical reality of the player.
The game should help the player discover the space of the square: the details, sounds, movements, the people.
Keep it simple.
Have fun!
