Its purpose is to create a game media ethics, free, online, which helps to educate and involve all stakeholders "consommacteurs" (students, company employees, teens, parents & grandparents) to three dimensions of sustainable development (social, economic, environmental) through their daily actions.

Through an avatar which the player is online live scenes of everyday life, he can understand the logistical and technical challenges related to his behavior. It has the power to act accordingly, at home or near home, individual or tribe, and compare his actions to those of others on relevant criteria and across many users, ( creation of "communities" of French players online, followers of sustainable development practices).
