Richard Davey's BristolJS presentation on HTML5 Game Development with Phaser.
The third section of the talk is all about Phaser 3, and where I see it going in the future. I also cover some of the considerable challenges involved in maintaining an open source project the size of Phaser. There is also a Q&A session at the end.
Note that there is a tiny bit of bad language as I despair about the state of my inbox, but on the whole most the video is clean :)
