Hey Marrsho, do you have your mini-campaigns written down, in any format and level of detail? If yes, I would love to read them. Looking to set up a test session with my daughter and her friends.
Hey frain! No, I don't, for that's the specifics of that kind of system – the adventure is created collaboratively in the process. You all are authors, unlike "classic" games, like D&D, where you have the pre-written scenario and basically you are the only narrator. You just have to try it once and trust your players, in fact, RPG newbies play that kinds of systems the best because they don't have thinking cliches from other RPGs, and just let their imagination out :) But you have to know the basics of HP Universe (movies are enough in fact) and if you need ideas about villains and their plots, you can read https://harrypotter.fandom.com/
Also, listen to the podcast above, the last 30 minutes or so is the mini actual play from David. It really helped me.
Here's a 4 session long actual play aswell. Wish you the great game! I'm sure you will have a lot of fun! :)
Thank you for the explanation and resources! Knowing that movies are enough to master this game, from someone who already mastered campaigns, is reassuring. I understand that I must spend some more time reading & watching about the HP world, before the first session. It will be a pleasure to do and increase the probabilities of a successful test session.
