When the Pandemic hit, I transitioned my live Planescape game over to Roll20, but we used Discord for voice. I ended up running a Planescape-flavored interpretation of Descent into Avernus. Even though we have resumed live games, the convenience of short online sessions wound up in me running 2 PS campaigns, with different parties (though individual characters have bounced back and forth between them). In person we meet 1 time a month if lucky, but can game much more frequently online.
Most of my resources are things I've cobbled together from online sources over the years and hand-converted materials from ye olde 2nd edition physical copies (we're playing 5th, though we did play a heavily modified 4e years ago. The game has been more-or-less going for 10 years now).
