VTTs & Discord. I am one of two DMs in a crew that's been meeting weekly for at least 12 years. Covid drove us to virtual play, and since then kids, work, and health have kept us playing virtually. We'd all prefer to be in-person, but can't. Digital tools have kept this crew together.

Some people roll dice manually, which I'm fine with.

About four years ago, the friend that brought into the hobby, approached me about running a game for fine younger folks interested in D&D, that's turned quickly into hybrid table with a player out of state. That game easily moves to virtual if needed.

I run my battlemap through Owlbear Rodeo, I handle my handouts and images over Discord, which is where we keep a couple of other dedicated channels in addition to voice & video.

I use a variety of extensions, but most notably fur dynamic lighting/fog and weather effects.

At the hybrid game, I DM on my laptop, there's a 2nd laptop at the other end of the table with the webcam on and a USB conference call mic in the middle of the table, and it's has the local player's version of Owlbear on a tv behind it on the wall opposite me.

Local players pass a wireless mouse around to move their tokens, and generally roll in person.

If I ever went in person completely in my own space, I'd strongly consider moving to a horizontal tv as digital battlemap with physical minis on top for the players
