First of all, I am under no delusion that there aren’t already 10,000 gaming blog posts called “Rule Zero,” and that they are generally about “The GM is always right,” or that “The GM can say no to anything,” so let’s just recognize that and move on.
Moved on? Great.
I invented something called Rule Zero.
Rule Zero is simple: You can try anything.
So, I’m a big fan of rules-as-roadmaps (RAR) instead of rules-as-written (RAW). Rules are there to guide both the player and the GM, to give action meaning, to establish strategy and consequence in the game world, and, as a last resort, to answer questions and respond to disputes at the table.
GMs should make rulings. These rulings may originate from their deep knowledge and implementation of the game mechanics, from random dice results, or simply off the top of their heads. In any of those cases it’s the GM making a ruling. That’s what they are there for.
But why are we collectively at the table? For fun!
Let me go back real quick. When I played my very first D&D campaign (as a player) once upon a time, I tried to do something. My character was on a small roadside cliff-edge above an enemy. I decided to jump down, swing my club, and allowing gravity and momentum to give me a boost to the attack. I had the high ground, and I was a larger creature than what I attacked. It seemed reasonable that this action-oriented type of attack would grant my character an advantage.
It didn’t. There was no official rule that said anything about having a bonus to one’s attack based on environmental elements or improvised action. My character didn’t have a specific “leap attack” or anything of that nature. Because the rules didn’t specify that I could do this, I was met with “You can’t do that.” I was penalized for creativity, immersing myself in the environment, and thinking outside the “this is what your class can do” box. A basic melee attack–clearly spelled out in the PHB–would have been a better choice with this GM. RAW screwed me.
This experience left a bad taste in my mouth, and eventually it helped lead to developing a system without classes. As a player, I never wanted to be limited ever again.
As a GM, I never wanted to limit my players, either.
This is where Rule Zero comes into play.
Rule Zero: You can try anything.
Failure is still a possibility, of course. Just because you can try doesn’t mean you can succeed. But the spirit of letting anyone attempt anything was built into BASE12 from the very beginning. In Shattered Empire, anyone can attempt a Skill check, even if they don’t possess that Skill; or rather, everyone has every Skill, but that Skill may be at level 0. You don’t have to be a Class to make a certain type of attack. In fact, even characters without training in a weapon or armor can still wield or wear that item. Training makes you more likely to succeed, but even a child can pick up a stick and try to hit an Ogre with it.
When I GM, one thing that I try to get across to my players is that if they can convince me that something is possible or “realistic” (relative to the environment) then they can succeed. Sometimes I’ll ask them for a Skill check without telling them which Skill. “Which Skill?” they may ask. “Whichever one will make you succeed at what you’re attempting,” I reply. Three different players may end up using a Search check, a Survival check, and an Arcana check based on individual character backstories, play styles, or critical thinking. It’s the same Skill check, but they are each rolling different Skills. Now as a GM I could have said “Everyone make a Search check to find the hidden cave entrance.” Maybe one of them has a good Search rating, and the other two are just going through the motions. Or maybe they wouldn’t: “You roll for it, my Search Skill is only 1.” It doesn’t connect the player with the character to be told what to try. Even if they suck at Search, if that’s what they choose to use for their Skill check, they’ll have a connection with their character knowing that they are struggling to do something they don’t excel at, instead of mindlessly following the GM’s instructions.
So, Rule Zero is really about experimentation, creativity, and problem solving. It’s about using the rules as a guideline, and not as a forcefield. You can try anything, and perhaps as an addendum, if you can convince me (the GM) you succeed. And, as always, it always comes back to what is the most fun.
