The fifth assignment is optional. After creating their initial concept, teams need to reflect on this design by taking the criteria of each world into account. Of course, it is difficult to judge certain aspects of a paper concept but it is still important to think about it.
With this assignment, teams need to motivate how their concept deals with the criteria and they may revise their initial concept based on these reflections. In other words, in this assignment teams are actually starting to balance their design with the criteria from each world in mind.
By looking at the criteria it may, for example, become clear that inserting a Dopefish in a game is not very relevant but kind of fun!
