You can visit the landing page for BGG.CONline — with this being our landing page in the future for all live events — to see the list of guests scheduled for airtime on May 20-21, as well as the games they will feature. (The listed time on the schedule matches your own time zone, so you don't need to adjust anything.)
We're starting with two of the Spiel des Jahres jury members, who are joining us from Germany to talk about the recently announced nominees for the Spiel, Kennerspiel, and Kinderspiel des Jahres awards, then we'll be joined by publishers who will give an overview of recently released games.
You can watch the Twitch broadcast from the BGG.CONline landing page, and if you're already logged into Twitch, you can comment on that page.
Hope you'll join us for the first of what will likely be many such online events!
