I gave my talk yesterday.
There was also The LibreVR Project talk. It was hard to understand due to streaming issues. He showed a 3D maze program using ascii graphics. I understand if you can get that working you can get other 3D programs working but it seemed like a very low tech game to show.
Empowering community-oriented play with TRBot was interesting. It's a bot to allow you to use chat to control a game. You can setup a twitch stream where the audience plays the game.
I don't see anything game related on today's schedule.
