I've been playing RPG's for about a decade and a half now. I've mostly DM'd in recent years. Most of it, on both sides, has been D&D, particularly 4E and 5E, but I've also done a fair bit of the various Star Wars games (I actually got my start by playing Star Wars!) and various other games.
I'd prefer to play at first, until I get the hang of Roll20. I can (and probably will) look into DM'ing after that
