Accessibility
We believe that accessibility in video games is an important component to creating a great game. Here's a great article on why accessibility matters. We encourage teams to use the Godot Wild Jams Accessibility Guidelines Basic List and check off features as they develop their game. You can view the full accessibility guidelines here.
AI Generated Content
The 20 Games Challenge as a whole is about encouraging creativity, self-learning, education and pushing your own boundaries. While some members of the 20 Games community have used AI Generated Content to great effect, within their job or to supplement areas outside their speciality, AI Generated Content as a whole goes against the overall goal. The ethics of the way the training data is harvested and stolen from artists, the bonkers water and electricity cost or the knock-on effects of electronics costs are just some of the considerations taken.
AI Generated Content of all kinds is BANNED from the 20 Games Challenge Jam
- Images, Videos, Text, Music, any possible content is included within this
- This also includes Code. Turn those Co-pilots off
- If there is a gap in your skillset we highly encourage cooperation and teaming up
