Climate Change Jam: Trial & Error

[Deutsche Übersetzung]

Why a jam about climate change?

Climate change is one of the most pressing issues of our time! And what do games have to say about it? So far: Not very much apart from post-apocalyptic scenarios. We want to change that and create creative, exciting, fun and thoughtful contributions with you. Therefore We promote the connection between games and science and make games visible that deal with the topic of climate change.
Are you afraid of climate change? - Make a game about it!
Do you have any interesting statistics that impress you? - Make a game about it!
Are you trying to explain climate change to friends and relatives? - Make a game about it!
You like Fridays for Future, but you don't have time for demos? - Make a game about it

How does the jam work?

Our Jam is a warm-up for the game convention "Halle of Games" in cooperation with the Silbersalz Festival in Halle an der Saale in October. But you don't have to be there - the jam itself takes place online.

"Halle of Games" will take place on October 18 and 19 with talks, workshops and an exhibition. Until then, we want to jam with you and show the best games on site.

Climate change is complicated!

Climate change is such an incredibly broad field of causes and effects - where to start? We support you during the four months of Jamming with regular input, online workshops and a community! 
For this time we are building a slack channel where we can meet and discuss online. In the channel we will also speak German - but don’t worry, if you have a question we can reply in English, too!

What games should be created?

That’s up to you! In addition to games, we are also looking for board games, card games, social games, interactive comics, VR applications and apps. Everything goes!

We want to get to know you and support you on Slack. This is not a requirement - if you just want to make a game, totally okay.

And if you have any questions or if you are looking for people to jam with, you are at the right place on Slack!
