Mechanics inform the playstyle

My group and I tend to play a lot of different RPGs and get exposed to a lot of different ways of handling the same design problems. How do you represent health? What do you roll for deception? How do you handle combat? How do you differentiate between different character types? How do you handle XP? How a given system handles these things and how much space is devoted to various things informs what game you will be playing.

Combat vs talking and the Edge system from Savage Worlds

We started running our Ravenloft game (Conspiracy at Krezk) using Savage Worlds system, mostly to test the waters before we delved deep with Savage Rifts and Rifts vs Star Wars. We aimed to create some more down-to-earth characters that aren't just some combat-focused adventurers. We hoped to find a lot of interesting options due to the large amount of books in the Savage Worlds roster and the system's popularity for making an interesting range of characters. As it turns out, a lot of the areas I wanted to take my character were severely limited.

In Savage Worlds, the system revolves around Skills and Edges. The first just inform what die you roll. The second are some more unique perks your character can take to augment a given playstyle.

I was thinking about making a character that could talk well to people. The options for that were being Attractive, being Very Attractive, being a Noble, or being Charismatic. All except Noble just give you +2 to roll, which is the blandest thing you can get from an Edge.

Now, what are my options if I want to be a combat character? Block, Improved Block, Brawler, Bruiser, Combat Reflexes, Counterattack, Improved Counterattack, Dodge, Improved Dodge, Elan, Extraction, Improved Extraction, First Strike, Improved First Strike, Florentine, Frenzy, Improved Frenzy, Giant Killer, Hard to Kill, Harder to Kill, Improvisational Fighter, Killer Instinct, Level Headed, Improved Level Headed, Marksman, Martial Artist, Improved Martial Artist, Nerves of Steel, Improved Nerves of Steel, No Mercy, Quick Draw, Rock and Roll, Steady Hands, Sweep, Improved Sweep, Trademark Weapon, Improved Trademark Weapon and Two-Fisted.

Similarly, there is a lot of emphasis and page count devoted to armour, weapons, combat vehicles, combat manoeuvres, healing, movement rate, as well as different monsters and burst templates you can apply. Talking to people is 1 page in this 161 page book.

Unsurprisingly, the system was only useful when we engaged in combat and didn't do much for us in other situations. After a few sessions our characters that didn't want to specialise in combat have ran out of Edges to buy that would be meaningful to them. In the end, this wasn't the best engine for the game we were trying to run - one focused around mysteries, exploring the unknown and people getting in over their heads. For that, we had to switch to...

The Lovecraftian horror of Chronicles of Darkness

Chronicles of Darkness is the second edition to the New World of Darkness line, which itself is a successor to the Old World of Darkness line. While the old systems used to be very min-maxy, the new one is less so.

We switched from Savage Worlds into Chronicles of Darkness after one season of our game and the game turned from being an eclectic group of adventurers into a more Lovecraftian tale. The Humanity system forced us to deal with facing off against horrors, dealing with slow erosion of mental sanity, dealing with lingering wounds and so on. On the flip side we also had characters that could persuade people by leaving themselves vulnerable to favours, foster a network of contacts among the militia, or even a character that just built themselves a safe library to study the occult. And all of that felt great!

All of these were natively supported by the system. While in Savage Worlds we most likely wouldn't be using any of these since the rules did not cover them, in Chronicles of Darkness we embraced them since they were right there, and our playstyle changed.

Violence as language in Broken Worlds

Broken Worlds is an RPG set in the Kill Six Billion Demons world. The system is heavily inspired by the Wuxia genre of fiction, and as such, the game revolves around martial arts and thus combat. We gave this game a try and the expectation pretty much matched reality - it was a system where you were expected to engage in combat, let your fists do the talking and communicate via violence. So if you'd go in and expect to have an adventure in the vein of Riki-Oh: The Story of Ricky, you would be in the right place. If, however, you'd try to use this system for say, our above example of a more down-to-earth Lovecraftian story with mystery and intrigue, you would be sorely disappointed.

Monopoly and selfishness

Mechanics inform not only the playstyle in RPGs, but the same could be said about board games. And what better example to use than Monopoly:

In Monopoly, the rules incentivise you to be ruthless and cut-throat to win. Even if a player is a nice person in real life, when you start the game, you will inevitably turn into a jerk, because that's how you win. Mechanics inform the playstyle.

Conclusions 

The mechanics of a system inform the playstyle of the players. A system with a heavy emphasis and page count dedicated to combat will inevitably work better if you focus on said combat. If you want your players to engage with your story using something other than their weapons, you should use a system that incentivises non-combat solutions. While you can always pull the "just roleplay it out" card, everyone will often try to resort to the path of least resistance and go with the listed mechanics with predictable outcomes rather than more nebulous "I think this should work but the rules don't say anything about it".

If you are a game designer, keep those things in mind - don't just grab one system of mechanics and expect it to make your game play the way you intended. Look at what you want the players to experience and roleplay while they play your game and then either find a system that caters to that, or make one yourself.
