New Rules Have A Time and Place
For games with lots of rules, it important to consider where those rules are listed in a book, and how they are presented, organized, indexed, cross-referenced. This can often lead to chicken-or-the-egg issues, such as when you want to explain how actions work so people know what you are talking about when you explain how many actions it takes to reload a weapon, but you want to present some examples of things like reloading weapons to give context before you explain how actions work.
The end result is often a compromise, especially in game with multiple people designing, developing, and editing them.
For expansions to a game, like big books of new options for RPGs, it’s important both to stick to the kind of schema you used in the core rulebook (because that’s what people who need expansions to those core rules have already learned is your organizational standard), and to make sure that if you add brand-new things, you do so in the right place, and at the right time.
For example, if skills are broken into a number of different tasks in the core rulebook, chances are each set of tasks is presented with the relevant skill. But if you are introducing new skill tasks (but not new skills) in an expansion book, there won’t be exactly the same kind of section defining skills. But most likely if “Skills” was a chapter before (or otherwise had its own header—see my Writing Basics on headers), you want to recreate that header, with a new introduction nothing these are just new tasks, rather than whole new skills.
While all that seems pretty intuitive, there’s a corollary that I see violated surprisingly often, especially from writers who mostly work in supplements rather than doing a lot of work in core rulebooks. That is: DON’T introduce new expansion rules anyplace OTHER than a logical niche where you’d expect to find all such rules.
Let’s give an example.
Let’s say you have an RPG with a skill called Riding, which covers everything regarding the care and use of mounts. It outlines how you train a mount, how you get a mount to perform better, control a mount in combat, and so on. All fairly reasonable, and intuitively if a player wants to know how to interact with a mount, this seems like a reasonable place to look. (A lot of that could also be in a Combat section, but let’s assume in this case the game organized around skills.)
However, there are no rules for hanging down to one side of your mount to use it as cover against ranged attacks.
Now, a year after the RPG comes out, you release an expansion book. In this book you have a new piece of equipment, the combat saddle. The combat saddle gives you a +4 bonus to skill checks to hang down on one side of your mount to gain cover against ranged attacks. And since there are no rules for that, it gives the rules.
And that’s a problem.
No one knows to look at equipment for new combat uses of the Riding skill. And unless the combat saddle entry is extremely clear, there are going to be people who feel you can ONLY attempt this maneuver with that saddle. (And they’ll have a point, since having a piece of equipment give you a new option you CANNOT attempt without that equipment is one of the cases where putting rules in equipment makes perfect sense).
Sometimes the issue is even worse, because the combat saddle may only give you the new rules in passing, so they don’t really seem like new rules. Like if it says “You gain a +4 bonus to a Difficulty Class 15 Ride check to use your mount as cover,” then it sure SOUNDS like that’s just a quick reference of rules that exist in a full form later… but they don’t.
And goodness knows there are lots of ways for this to happen. Sometimes game writers believe the ability to do something is obvious even though it’s never spelled out. Sometimes they misremember rules, especially if a rule was changed from a previous edition or cut in the development of a book. Sometimes the plan was to reference the new rule in 3 places but there wasn’t room in the book so it got cut back to just 1 reference… in a bad organizational spot.
There’s no one cause of this problem, and no one solution to avoid it. But it’s worth looking at, as a writer, designer, developer, and editor, to avoid adding rules in weird places.
Especially in expansions.
