Ecity is an Expedia Japan passive game campaign. Basically, the user create a virtual city and have nothing else to do than sharing his personal game url to play. Every time a new visitor will visit his page, the city will grow. So the more visitor you have, the biggest is your city!
The Main part of the game is made of Flash/AS3. The site backend is (of course) a symfony project, version 1.2. This guys communicate via AMF. Each user got his own unique sub-domain URL, making the thing easier to share.
Of course, this project was more than inspired by the great work of the Motion-Twin guys.
This project is not online anymore.
