DISCLAIMER: the following is, like, just my opinion, man. I'm not one of those people who are, like: "do it this way or you're a moron". I'm a nobody, I've never written or done anything of value in the hobby "community". So if anything that I say makes your monocle pop out and shakes your jowls in anger, take a deep breath and just realize that I'm just some random jerk on the internet who doesn't know SHIT. K moving on. For any long-term campaigns that I've run, including a Session 0 has proven to be beneficial to me for the following reasons: People make characters together, giving them a chance to fill in any gaps for party "balance". We avoid too much overlap. People discuss what their expectations are about the campaign's themes, style and mood. This includes me. We figure out how the characters are grouped together, as vaguely or as detailed as we desire. Saves us some time and it even allows a bit of shared backstories creating greater party unity. We might even indulge in some sacrilegious collaborative world creation. After session zero, though, that stops and the GM goes hog wild. The players just help set the stage. For some, however, this is a colossal waste of time for all sorts of reasons: all that stuff should happen through play, not through meta-gamey magical tea parties. the GM is wearing the viking hat and so the players should shut up and roll with the punches "true" campaigns are supposed to be highly lethal so why bother with anything more than the most superficial character bonds and shared backstories? Fuck balance etc... "Collaborative" and "world" should never be in the same sentence spoken by a GM, ever. It is interesting to me, but not surprising, that techniques that work super well for me are unused or even despised by other GMs out there. I'm interested to hear what other people think of Session Zero, or how they run it themselves. My mind won't change: I love Session Zero as a concept (perhaps not for every single campaign ever). But I like to expand my mind with other opinions! So how about it? Do you like using the Session Zero Technique? What sorts of activities do you set out to accomplish with it, assuming that you do use it?
