Debate fuels my Fire
I have been tempted to run Princes of the Apocalypse a number of times. I think it would require quite a bit of prep, so I haven't done it yet. If this group seems interested in continuing to play after a few sessions, this may be the next step. I do have the full adventure. Are there things in the free version that are not included in the book?
There aren't, no. It is more of a sandbox than Dragon Heist or Phandelver, so will require more prep.
