Doug E. said: DMing on Roll20 is much more work than an in-person game in general as you need to create all the maps, NPCs, etc. That's if you use maps and sheets 'cuz you could use the Roll20 environment just to roll dice and have the game "Theatre of the Mind". Having said that, there is the option of buying pre-gen modules from the Marketplace but there is nothing from WOTC that is officially licensed there. I couldn't disagree more. If you triple the standard minimum for VTT-games, it doesn't mean that it takes 3 times the amount of work to prep a VTT-game. It means you just tripled the standard minimum. It definitely takes time to learn how to use Roll20 but after I got used to what can be done and how, I have found it to be easier and faster to prep and run (identical) campaigns in Roll20 than face to face.
