On the diplomatic layer, the player has an opportunity to present drafts for policy changes to the EU(for issues such common immigration policy, stem-cell research or agricultural quotas). The discussions about these changes take place in the classroom, where they are moderated by the teacher, who can also give short lectures and contextualise gaming issues. Every player has his/her own project to try to push through at the European level. A project is basically a vision of how the EU should look in the future and it is formally defined by: (a) a set of policies that should be put in force, (b) a set that should be suspended, and(c) a set to which the project is indifferent(e.g., the Green Europe project supports environmental protection and investment into alternative power resources, while the Conservative Europe project strives to preserve traditional values). From the gaming perspective, projects present roles the students can play. The important aspect is that every player can choose his/her project. Because some projects agree or disagree upon the same subset of policies each player can find a team-mate to support his/her intended particular policy change. The final appearance of Europe at the end of each match is thus the result of intense negotiations and voting in a given player group
