Coming back to make my first post here in years
I saw on Facebook that Doug Burke had passed away. I don't have any details. There is a GoFundMe for his kids at https://www.gofundme.com/f/the-children-of-doug-burke.
I never had the chance to meet Doug in person, though I've known him since the 1990s and always enjoyed interacting with him. I actually had the chance to game with him for a few sessions of my first Star Trek Adventures Campaign early this year, and I'm so happy I had the chance to do so.
