I'll be running a Mothership RPG campaign soon, and will start off with a Session 0. Anything I should be sure to include? Might do a oneshot as well if there's a bunch of time, this is our first time with this system and my first time as a GM. Thanks!
I found The Lazy DM's guide quite useful. It has a lot of advice on various parts of running campaigns, including session 0. It assumes you'll run 5e, but I've found it useful even after I switched away from dnd. I can share the pdf with you if you'd like, send me a PM if so.
Thanks, I'll take a look at it!
