GGJ19 Diversifiers

Once again we have wracked our brains and developed some excellent community submission to create the 2019 GGJ Diversifier list!

We hope these will get you fired up and excited about the Global Game Jam in just over a weeks time.

With big thanks to the following people for helping to make this possible: Alex Camilleri, Sarah Cole, Rebecca Fernandez, Ian Hamilton, Eddy Léja-Six, Daniel Linssen, Shalev Moran, Tim Stobo, Claire Wilgar and Sagan Yee.

Together they helped to come up with an excellent list, along with all of you who responded to our open call for diversifier submissions this year. 

Diversifiers are a great way to add a little more fun or challenge to your jam weekend. Sometimes they can be very helpful to limit your scope or refine your ideas. They are totally optional constraints you can choose to add to your GGJ19 game alongside the main focus of the theme. It can help your game stand out from the crowd, and you can choose up to 4 when you submit!

This year's diversifiers will also be available in other languages,  which will be linked to this post as soon as they are avalible.
