For Magonomia ®, we developed something we call the Platinum Rule:

All players share responsibility for making the game fun for everyone.

A lot of RPG players and GMs understand and use this rule already, of course. Strangely, I have never seen it written down in an RPG rule book in quite this form — many games address making the game fun for the players, but usually that’s framed as solely the GM’s job.

Why the Platinum Rule?

I’ve tried to make our game accessible to new RPG players and to players who might want to re-enter the hobby after a long absence. Therefore, I thought a lot about how to present the rules to make the essential concepts clear. The Platinum Rule emerged as the most important concept I could think of that I wanted to communicate. This is the one principle that I most want to share with the whole RPG community. It’s the distillation of my 40 years in the tabletop RPG hobby.

Now that it’s occurred to me to write it down, I am rather puzzled that I haven’t come across something like the Platinum Rule more often in other games. I have certainly seen language to the effect that the GM is responsible for making sure all the players have a good time — but that places all the responsibility on the GM. If you think about it, players have a great deal of impact on the quality of one another’s experience. That is both a responsibility and huge opportunity.

It goes without saying that the reason for playing the game is to have fun with your friends. We think it's useful, though, to make that idea explicit and examine it.

This is the only rule that's really important: all players share responsibility for making the game fun for everyone.

The implications are far-reaching. How do you, as a player, get to have your character shine without upstaging the other characters? How do you encourage a shy player to participate without being pushy? As a GM, how do you know when you're making things too easy or too hard?

What is “fun,” anyway? Different players will have different priorities. Some want to solve challenging problems, some want to immerse themselves in an imaginary world, and some want to create a rousing adventure tale. You’ll need to discuss this a bit so you can make sure everyone can get what they want out of the game.

Roleplaying games are a hobby. Everyone, new or old, develops their own style. That means everyone, including you, has something unique to offer. The best experience comes when you realize that you can contribute to making the game awesome for your friends.  

Bad Habits to Avoid

The Platinum Rule is primarily about making positive contributions, but there are some pitfalls in roleplaying that are worth bearing in mind.

Don’t hog the spotlight. Some people are naturally more assertive than others. Go ahead and have your character be awesome! Just make sure everyone else also gets their moments to be the star.

Don’t undermine other players. Don’t make choices that directly contradict what another player has started to do. For example, if one of your fellow PCs has started to negotiate with an enemy, don’t suddenly interrupt and challenge that enemy to a duel. If you really want to change direction, ask permission.

Don’t make a character who’s a jerk. You control what your character is like, so you’re responsible for whether they’re a positive or a negative influence. This is not to say your character can’t have personality flaws – a flawed character is often the most enjoyable and rewarding to play. Just make sure your character is likable in some way and can work well with others.

Good Habits to Cultivate

Giving a list of advice on how to be a good roleplayer may seem overwhelming to some (and superfluous to others). It’s certainly sufficient to start with the Platinum Rule and just apply it as you think best. If you want some more specific suggestions, here’s a list you can refer back to from time to time to help you develop your collaborative roleplaying skills.

Keep the story moving. As long as everyone is enjoying themselves, the game is going well! There will come times when the game session feels stalled or goes completely off track. When you notice that happening, say something or have your character do something to refocus people’s attention on the story. This is everyone’s job, not just the GM’s. If your group is having trouble making a decision, the General Divination spell is a powerful tool for getting past that impasse.

Yes, and… The first rule of improv theatre is to accept your partner’s idea and add something to it. You will find many opportunities to do this as you play. Aspects and Fate Points, explained later in this chapter, are a game mechanic for creating “yes, and” moments in the game.

Give positive feedback. When another player or the GM does something great, say so! This will help build a shared understanding of what your group enjoys.

Embrace setbacks. There is more to a good story than having your character go from success to success. A good story needs moments of tension! Some of the best experiences in a roleplaying game come when the heroes have to claw their way back from the very brink of destruction. Don’t be afraid of bad things happening to your character. Be afraid of letting their story become bland and forgettable.

Show your character’s reaction. Showing or describing how your character reacts to what’s happening around them is an easy and powerful method for engaging everyone in the story.

Learn the rules. Nobody expects you to memorize everything in this book – even the authors have to refer to it frequently during play. That said, the better your grasp of the rules, the more you’ll be able to apply them creatively. Spend 10 minutes re-reading sections of the rule book before each game session and you’ll probably be surprised how much that helps.

Being a Great Player

A good player doesn't interfere with other players' fun.

A great player actively promotes other players' fun.

If you try to be great, you will probably succeed.

Applying the Platinum Rule

The Platinum Rule only works if you talk about it. It doesn’t have to be a long conversation. Just introduce the concept and make sure everyone knows it is part of your group’s social contract. During that conversation, it’s a good idea to invite the players to volunteer what makes the game fun for them. Focus on the positive, to encourage players to start collaborating.

I find it especially helpful in breaking the ice at convention games, where players may be meeting for the first time.

Something particular to Magonomia ® is that it’s a historical fantasy game, and a lot of gamers will understandably hesitate to step into a setting based on a time that’s so strongly sexist, racist, anti-Semitic, Islamophobic, and generally nasty compared to our own. The Platinum rule is a very tidy shorthand for how to make even a historical fantasy setting safe and welcoming. If something wouldn’t be fun for everyone, then don’t bring it up at the gaming table. Simple enough?

Related Subject: The X Card

I would never have thought of the Platinum Rule if I had not been taught about a similar and very useful concept, the X card, at Gen Con 2015. I definitely recommend you use the X card in addition to the Platinum Rule. They compliment one another.

Why It’s Called the Platinum Rule

The reason we called it the Platinum Rule is simple: Magonomia ® is based on the Fate™ Core System and Fate™ already has a concept called the Golden Rule of Fate. In other words, the term “Golden Rule” was taken.
