For the majority of the games I’ve run in my tenure as a GM, we had a perfunctory session zero, if we had one at all. In the early years, I was seeing my players throughout the week, and we’d have piecemeal discussions at random to talk about the upcoming game. Lately, however, I’ve taken to setting up a robust session zero with everyone present, and I’ve found it invaluable.
But, I noticed one snag in the process when I was making that switch. There’s plenty of discussion about the value of session zero on the internet, but I didn’t find a good blueprint anywhere. That’s why we’re here today: we’re looking in depth at session zero. What is it, why should you do it, and when should it be.
What is Session Zero?
Alright, say a gaming group is starting a new campaign. They just finished a published adventure and are deciding which one they might want to run next, or they’ve reached the end of a homebrew game and everyone is ready for new characters, or maybe it’s just been several months since they played last and they need something new to get back into it.
In all these scenarios, there’s a lot of different paths they could take. Maybe the group that runs published adventures just dealt with Strahd and they want a change of pace – something more laid back or comedic. Maybe the homebrew table wants to try another system. Perhaps the group that fell into a hiatus has been able to identify what wasn’t working in that last campaign and everyone wants to get on the same page.
For all these reasons and many more, hosting a session zero is the best way to discuss these topics. It needs the same respect as a normal gaming session: full focus, phone set aside, snacks at the ready, ideas prepared. Then you’re ready to begin.
What should we discuss for session zero?
Foremost, you should discuss your ideas for the campaign. Things like tone, themes, setting. If you have several discrete ideas that you’re equally interested in running, this is the time to talk about them and see what your players latch onto.
As an example, last August one of my players was going to be away for several weeks, and a friend-of-a-friend was interested in joining our campaign. Rather than go on hiatus, I ran a small scale campaign to introduce that friend to D&D. Our main campaign had reached the higher levels by this point, and my players and I were looking for a brief change of pace. So, session zero, we set the tone: this was a game for goofs and jokes. We decided the PCs knew each other – tangentially, at least – and that they’d been on a bender and lost their employer’s magic item. As part of session zero, I asked them each to tell me in secret one reason they might have stolen the magic item. They each remembered their own problem, and they used those hooks they generated to try and track the item down.
For players at session zero, I recommend arriving with a few ideas about the kind of characters you’d like to play. You’d hate to show up to a party dressed in the same thing – even in a mono-class kind of game, you’d still want your PCs to have specific strengths and weaknesses. Pick a couple classes, develop a concept that works with multiple classes, or come with a few different ideas and build a party that can work well together.
And, as implied above, discuss the campaign at large: what’s the trajectory? Are we heroic or villainous or just trying to get by? Is there a level range we should expect to conclude around? Decide what system you’ll use, discuss house rules; if there’s a mechanic you mean to make the backbone of your character, clarify that you and the GM interpret it the same way.
Perhaps most importantly, decide what’s off-limits. I have a hard rule against any portrayal of sexual assault. I had a player with arachnophobia who asked for limited spider encounters (and less descriptive narration for spiders). Do the players want to deal with racism or homophobia from the NPCs? – Are you as a GM comfortable portraying those kinds of people?
Session zero is the time to set everyone’s expectations in the right place, so everyone can engage with and enjoy the game.
When should you have session zero?
I think the best time to host it is one or two weeks before beginning the game itself, during your planned session window. Naturally, if your group meets less often, than just that first meet-up should be session zero, with the game beginning the following meet.
Any other tips?
My main goal in hosting session zero is to understand the PCs as much as possible. With that mini campaign and my upcoming game, I really wanted the direction of the game (at least at the early levels) to be player-driven. I want them to tell me their goals and desires so I can put them on pathways toward those items.
So. That’s my advice on session zero. I hope it helps make your games better. As always, thank you for reading! Good luck out there, heroes.
