I'm new to Roll20 and so I'm not sure how it works. I have a local group of players and I wanted to buy a campaign through Roll20 in order to utilize the pre-built maps for the campaign. I'm not sure how it works though. My thought was I'd have a TV setup flat on a table and I would display a map and I can move the characters as they needed to be moved through a dungeon, all rolls and combat would be handled with real dice/paper. Is this possible with Roll20?
