The GUMSHOE system seen in The Esoterrorists and upcoming follow-on games and supplements can be used for any mystery or procedural game. We’ll be presenting new settings in the future, but in the meantime, the game’s core engines are easily adaptable to whatever investigative genre you want to run. Here’s how to adapt GUMSHOE to emulate your favorite procedural, whether it be 24, Torchwood, CSI, or The X-Files.

Step One: Study Your Source

First, immerse yourself in the property you want to recreate. You may be adapting a specific procedural, or drawing from a broad subset of similar shows. It might also be fun to combine the structure and tone of a well-known TV show with the genre elements gamers love: “It’s Cracker, but with werewolves.”

For the sake of a default frame of reference, I’m assuming a TV show here, but the general principles apply equally to novel series: you could just as easily adapt Sherlock Holmes, Ellis Peters’ Cadfael, Iain Pears’ art-world mysteries, or Tony Hillerman’s Navajo-centric whodunnits.

Creating your own original property requires less homework but is tougher in some ways. You’ll have to portray your setting and narrative formula to the players without the shorthand that comes with the shared viewing experience of a popular show.

Start by identifying the structure of your source’s typical episodes. Look for standard elements that recur from one episode to the next; these will help you to construct scenarios. For a long running property with many cast changes over the years, determine if the various characters fall into distinct types.

Make a master list of the various GUMSHOE investigative abilities. When one of these abilities, or a close analogue, comes up in the course of an episode, put a tick mark next to it. If abilities appear which have no counterparts in GUMSHOE, make a note of that. Pay special attention to the interpersonal abilities, which are easy to gloss over, appearing as they do in the ebb and flow of dialogue, interrogation and interview scenes.

Take note also of what the characters are able to do during non-investigative scenes. Again, note what GUMSHOE abilities you see in action, and which other abilities you’ll have to define for your game.

Gauge how competent the protagonists are. Are the action sequences, if any, over the top and stylized, or gritty and real?

As is often the case in adaptations to the RPG format, you may have to adjust a series featuring a single protagonist (or a duo) to make an entire team of characters co-equal centers of attention.

Step Two: Investigative Abilities

Take the list of abilities you’ve compiled during your homework. Note how fine-grained the technical and academic abilities seem to be. Is a big distinction made, for example, between the various forensic disciplines? If so, you’ll likely want to use a large list of abilities, as seen in The Esoterrorists. Otherwise, a more stripped down, general list likely suits better. Such a list appears in the upcoming GUMSHOE horror book, Fear Itself.

Look at the abilities you haven’t seen in play in your source material. Can you envision them ever appearing? If so, include them. If not, leave them out.

Certain forensic techniques will be unavailable in non-contemporary settings. Forensic entomology is a very recent sub-discipline, for example. An ancient or medieval sleuth won’t be looking for fingerprints. Other disciplines might be available in more primitive form, providing less information. For example, a photographic expert in a 1940s hardboiled game will have less to go on than his contemporary, computer-equipped counterpart. In some cases, you’ll want to rename abilities: forensic psychology might become alienism.

Once you’ve assembled your final list of investigative abilities, divide the number of abilities by the number of players who you expect will regularly attend your game, then add a handful of points to this total. This gives you the number of build points the players get to buy their investigative abilities during character creation.

Step Three: General Abilities

Repeat the above process with general abilities. Most basic general abilities will apply to any setting, but there are a few that need tweaking for historical genres. Pre-industrial characters might use Riding or Carting instead of Driving, for example.

(When in doubt as to whether an ability is general or investigative, ask yourself if it can be used to gather information, or to perform some other task. If it’s the latter, it’s investigative. If the former, it’s general. If what seems to be the same talent can both gather information and perform other tasks, split it into two, making it both an investigative and general ability. The prime example of this are the Reassurance and Shrink abilities, which resemble each other thematically but have different narrative functions.)

If your setting is gritty and realistic, give the players around 5 build points for each general ability. For a more over-the-top setting, assign 8-12 points per general ability. Some general ability lists will include specialized abilities that few PCs will want; if so, omit them when tallying your total number of abilities.

In certain fantastic genres, you may want to create a subclass of special abilities, like super powers or psychic talents. Write descriptions of these so the players know how they work. It may be that some are investigative and some general; be sure to indicate which is which. Assign them a separate build point total, reflecting the degree to which you want these talents present in your game. You will probably also want to limit the number of special abilities each player can take, or allow only a restricted number of PCs to have them.

Step Four: Conceptual Aids

If characters in the setting tend to fall into definable categories, write brief descriptions of each type, to help the players fit their characters to the property.

Look at what motivates the characters in the property. If necessary, create guidelines or rules structures to assist players in acquiring the necessary mindset. For example, Fear Itself character creation requires the players to pick the worst thing their characters ever did. This provides a plot hook to use in flashbacks and scenes of character development. It also requires you to pick from a list of possible motivations to take the apparently stupid risks that get horror characters into entertaining danger. A rule then provides an incentive for reluctant players to make the choices that drive stories of this type.

Step Five: What to Leave Out

Just because a rule structure is present in current iterations of GUMSHOE doesn’t mean that it will work for your property. Stability, for example, is essential for horror-based mystery games but inappropriate for all but the most punishing and gritty crime or detective properties.
