The rules will stay mostly the same, but the new approach this year is making the category a little bit more framework independent, or rather providing you other options to chose from. Last year’s category was organized with an incredible support from Mozilla, while this year I’m also partnering with Microsoft to bring you Babylon.js as the second tool of choice. You can now make a WebVR game with either A-Frame or Babylon.js - it’s up to you.
Another, but smaller difference (and A-Frame specific) is that you don’t have to worry about making your own fonts - you can use the ones A-Frame is downloading on its own in the background (which was forbidden last year). This is the only case changing the “no external resources” rule beside the frameworks themselves.
Why WebXR and not WebVR as the name of the category? For future editions, so you’ll be able to create for both virtual and augmented realities.
You can win three Oculus Go devices (read the rules for details on shipping), five Webstorm licenses, ten PlayCanvas accounts and fifteen custom cardboards. More prizes may still appear, so be sure to check WebXR landing page for updates.
Just like a year ago we will have a dedicated panel of judges - I’ll add all the names in the next few days.
