When You Alter Or Ignore Rules, It Changes The Game's Challenge

All of us are familiar with the first rule of RPGs (or the 0th rule, depending on how you count)... namely that if you don't care for a particular rule that you can just change it, replace it, or even toss it out entirely at your table. It's been my experience, though, that a lot of players and Game Masters take this as carte blanche to do whatever they want, but then they're surprised when the minor change they thought they were making ends up being the flapping butterfly wing that leads to a completely unexpected monsoon in another area of the game!

So, while you are absolutely free to change, ignore, or otherwise customize your gaming experience when playing an RPG, it's a good idea to ask why a particular rule exists in the first place, and how this alteration is going to affect things going forward.

No movement penalty? Oh I'm comin' for ya!

Change The Rules, Change The Game

I will be the first to admit, rule changes are not inherently bad. Even the professionals sometimes get things wrong, or maybe you just want to simplify something in a way that doesn't boomerang back and smack you in the head as a GM because the deeper changes to the rules never have an effect on the monsters you use, or the characters and classes your players pick. But it is important to stop and ask why certain rules exist the way they do, and to ask yourself what removing those rules does to the challenge of the game, but also to the balance you're working with.

For example, let's talk about wizards.

Say you're running a wizard in the first edition of Pathfinder, or in the 3.5 edition of Dungeons and Dragons (this example might work for other games and other editions, but I don't want to make assertions I'm not fully confident about). So, you are a prepared caster, and you need your spellbook in order to properly prepare your spells every day. That spellbook is both your advantage (since you can learn new spells from other books, and from magic scrolls), but it is also your weakness. If something happens to that item, you are in deep shit, as you can't refresh your spells until you come across a new book.

Most GMs aren't big enough dicks to deliberately target a wizard's spellbook, as that is a surefire way to upset and frustrate a player. However, even if you don't have goblins trying to snatch it away, or enemy wizards casting disintigrate on the book, there are a slew of other rules that we often ignore regarding this jarring weakness. For example, if a character winds up in the midst of an area of effect spell, like fireball, they're supposed to roll saves for particular possessions on their person... and for wizards, that often means a spellbook. There's also the question of what happens when a character's possessions are exposed to the elements, such as when they're thrown overboard into the ocean, trapped in a downpour, or just fording a river on their journey. All of these situations have rules that can affect character possessions (scrolls, black powder, alchemical items, rations, etc.), including one's spellbook.

This is the reason (not to shake my walking stick at the clouds) there were so many alternatives for wizards specifically, and for other prepared arcane casters in general. There were warded spellbooks, spellbooks made of specific materials, spells that kept your spellbook safe in a pocket dimension where it wouldn't be affected, tattooed spellbooks that would be safe as long as you didn't get your skin flayed off, and it was why some campaigns just gave you thick tomes of extra spells that you could use to copy over your existing spells, ensuring you had a copy back at the cart, the inn, your castle, etc. if something happened to your in-the-field grimoire.

A lot of us ignore these rules entirely for making separate saves for player equipment when they're exposed to particular hazards. And on the one hand, yes, that means wizards, magi, and similar characters don't have to worry about a single bad roll taking away an item they need. That also means they aren't spending their resources to ensure their books are safe from harm, and that they have back-ups in case something happens. It also means that the advantages of other casting classes like the sorcerer (who requires no spellbook, and often doesn't even require material components) are far less powerful by comparison.

I've run the numbers here... they check out.

This doesn't just apply to the one, specific example I listed. It also happens when you ignore rules that say spellcasters need one hand to hold a focus component, and one hand to make somatic gestures. This undercuts special class features and powers that let weapons, shields, etc. double as necessary components to free up a character's hands. Ignoring the requirements of a holy symbol for divine casters (something that is also subject to the above rules for environmental damage in many cases) devalues features that may give you tattooed or birthmark symbols that can't be destroyed so easily, or which may free up a character's hands for other actions. It happens when you completely ignore encumberance rules, and you have your party carrying a literal ton of magic and alchemical items into the next dungeon, and it happens when you don't bother keeping track of ammunition (special or otherwise), and you wonder why the long-ranged characters have such a major advantage.

Again, we can all run our games however we want to. It is important to remember, though, that game designers don't just make up rules to fill more pages and expand our book so it looks more impressive... rules are made to solve issues in the system. Kind of like the safety precautions you're supposed to follow at work. Yes, they might be annoying, or you might wish you could ignore them, but the powers-that-be required that rule because the boss kept putting barrels of toxic waste in the crew's sleeping quarters, or the machinery kept ripping off people's fingers... the alterations were made for a reason.

The easiest way to find out what that reason was is to ignore the rule, and see what happens as a result!

Players Change To Reflect The Rules

This isn't a white room thought experiment, either. If the rules shift, that has the potential to encourage players to use different avenues and mechanics to reach their goals. I told a story about this very thing happening in real-time in episode 34 of Discussions of Darkness, How Rule 0 Creates Ripples in Playstyles.

This warning is basically the other side of the coin. Because the examples I talked about in the previous section were all things that GMs could do to throw players a bone, and relieve the burden/pressure on certain classes or characters... however, when you institute rules to limit the effectiveness of particular options to control player behavior, players often find alternatives and workarounds in directions you might not have expected them to go.

For those who don't have time to listen to the full story in the video, it was about how Minds Eye Society limited the damage a single character could do in one strike. 5 levels of lethal damage was the universal cap, regardless of what someone's powers were, what magic items were play, etc. Whether it was a mortal security guard who got off a lucky shot, or a Promethean who threw an exploding tanker truck at someone, 5 levels of damage was the most that could be done... and since an average character has 7 levels of health, and 6 at a minimum, it became impossible to kill anyone outright with one attack. So players started investing in the ability to hire goon squads of their own, bringing teams of characters with tooled-up armories as back up and fire support. Because no one of them could deal a death blow... but if you have 10 elite troopers at your side, and you also get into the fray, well, now you've got superior firepower and a bunch of extra attacks on your side of the fight.

Change Requires The Whole Table

We usually think of rule changes as something the Game Master does, and that players have to deal with, for good or for ill. However, changing the rules of the game is something that should be done with the consensus of all players. If you want to change things up, explain why you think a rule isn't working, what you'd like to do instead, and make sure everyone has buy-in for it. Also, make sure that you make it clear that if this change doesn't work, or creates more problems than it solves, this is something you can come back to in the future and talk about more.

I've said this before, but it bears repeating. Everyone at the table needs to be playing the same game, and rule changes should be made with the consent of everyone so that each person believes this is more fun (and potentially more fair) than the system that's already in place. And while not every change is going to work, everyone should be onboard for it, and be part of the discussion for how to structure the game you're all playing.
