 Example 2: In the example above the set of players N is {France, Germany, Italy, Belgium, The Netherlands, Luxembourg}. If we consider the issue adoption of a border-protection scheme, there are two outcomes: yes and no, i.e., \(W = \{\mbox{yes, no}\}\). If we instead consider the issue millions spent on border-protection scheme there is a potentially infinite outcome space, i.e., \(W = \{\textrm{0M}, \textrm{1M}, \textrm{2M}, \ldots \}\). It is possible to have a set of outcomes that is even refined further, for instance specifying the way players have voted. In this case the outcome in which France vote yes, the others vote no, and the result is no, would be different from the outcome in which Italy vote yes, the others vote no, and the result is no, although the result of the vote is the same. What is important to emphasize is that each set of outcomes comes with a level of description of what is happening in the underlying interaction. There is no a priori right or wrong level of description, the choice depends on the properties of the game that one is interested in.
