The GGJ Diversifier system is a system aimed at diversifying the games as well as providing motivation for experienced game jammers. In a sense, the diversifiers are a free-for-all voluntary list of secondary constraints, that the individual teams can choose to go for, or not, as they please.
As stated above, the diversifiers are absolutely voluntary, and no points are given for taking them. If you are a first time team of students, we recommend that you focus primarily on the overall constraint, and only add in extra diversifiers if you feel sure you will have something to hand in on sunday.
