Unlocking Investigative RPGs and Mystery Solving, Part 2: Compelling Mysteries

Within the big ol’ tent of roleplaying, there is a subgenre that caters to those who enjoy unraveling mysteries, solving puzzles, and playing the role of a detective. Investigative RPGs offer a potentially very captivating experience, where players must use their wits, deduction skills, and keen observation to uncover hidden truths and solve complex cases. In this seven-part series, I’m going to have a wee look at investigative RPGs.

This is the second entry in the series and will focus on the compelling mysteries that our player will solve. Let’s remind ourselves of the plan for the series:

Let’s get to it!

Last time, we spoke about rules and gameplay structures. Rules are important; of course they are… They’re not the most important bit, though. In any RPG the rules are there to facilitate the experience of collaborative storytelling.

The real backbone of any investigative RPG is a compelling mystery storyline. Creating an engaging mystery requires careful planning and attention to detail. Game masters or developers must establish a coherent and logical chain of events, plant clues strategically, and ensure that the resolution is satisfying for the players. This section will explore tips and techniques for crafting immersive and thought-provoking mystery storylines that keep players engaged and challenged.

1. Planning

A compelling mystery begins with a strong premise that hooks the players’ interest. Consider intriguing concepts, unique twists, or unusual settings that will captivate the players from the start. Whether it’s a murder in a secluded mansion or a stolen artifact with mysterious powers, a solid premise sets the foundation for an engaging storyline.

With a concept established, we can then outline the key events and plot points of your mystery. Identify the major clues, suspects, and twists that will propel the investigation forward. Make sure the sequence of events is logical and flows smoothly, leading the players from one discovery to the next. Create a timeline or storyboard to visualize the progression of the mystery. here’s a simple example from Chaosium, publishers of Call of Cthulhu:

On top of that skeleton, distribute your clues throughout the game world in a way that keeps players engaged and challenged. Consider placing them in locations that are relevant to the investigation or in the possession of key NPCs. Ensure that the clues are not too obvious but can be discovered through careful observation, investigation, or the use of specific skills. Vary the types of clues, such as physical evidence, witness testimonies, or cryptic messages, to add depth and variety.

Of course, things should not be too easy for the players! Introduce red herrings and elements of misdirection to keep the players guessing. These false leads should appear plausible and lead players astray, adding an extra layer of challenge to the investigation. However, make sure the red herrings are not too frustrating or misleading, as players should still have a fair chance of solving the mystery. We’ll explore this in more detail later in the series.

With a structure set, including elements designed to misdirect, we can further encourage player agency by offering multiple paths and solutions to the mystery. Allow players to approach the investigation from different angles, using different skills, tactics, or strategies. This promotes creativity and ensures that each player feels invested in the outcome. Be prepared to adapt the storyline based on the players’ choices and actions.

Design challenges that reward critical thinking, deduction, and creative problem-solving. Encourage players to connect seemingly unrelated clues, analyze patterns, and make logical deductions. Consider incorporating puzzles, riddles, or complex mysteries that require players to think outside the box and utilize their investigative skills.

Ensure that your mystery has a satisfying resolution; tie up loose ends, reveal the mastermind behind the events, and provide closure for the players. A well-crafted resolution should feel logical and satisfying, and reward the players’ efforts and deductions.

2. Delivery

First and foremost, an investigation is far more interesting when there are consequences for not completing it in a timely manner. Introduce a sense of urgency by incorporating time pressure into the investigation. Establish a ticking clock, such as a deadline or an impending event, that adds tension and encourages players to make meaningful decisions and prioritize their actions. The looming consequences of failure can heighten the stakes and keep players engaged.

Still on timing, try to pace the release of information throughout the investigation. Avoid overwhelming players with an information dump, but rather let them gradually uncover the truth as they progress. This helps maintain intrigue and suspense, allowing players to connect the dots and experience the satisfaction of piecing the mystery together.

A huge part of the game will come from player interactions with other characters in the course of their investigation(s). Populate your mystery with interesting and memorable non-player characters (NPCs). Each NPC should have their own motivations, secrets, and relationships that can be discovered by the players. NPCs can provide valuable information, become suspects, or serve as allies or obstacles throughout the investigation. Flesh out their personalities and quirks to make them come alive in the players’ minds. I like to keep an index card summarising each significant NPC.

Final Thoughts

By implementing these tips and techniques, you can create immersive and thought-provoking mystery storylines that keep players engaged and challenged throughout your investigative RPG.

Remember that however much you plan, your players will subvert these plans in ways that are both annoying and magnificent. Allow for this. Embrace this. Love this. Next time, let’s focus on this with a discussion on player agency!
