My manager was a huge fan of Progress, such that it became the de facto tool of choice whether it fit or not.
I was less of a fan, but just checking now, it still exists! I'm curious about this one blurb from their web site though, which proclaims, "Progress Named a ‘Strong Performer’ in The Forrester Wave™: Low-Code Development Platforms For AD&D Professionals, Q1 2019"
I'm not sure how a database applies to sitting around with dice and figurines, but I've never really understood that whole pro gamer thing.
