A Hidden Reality: Exploring Ground Truth in Gaming

In the context of games and exercises, “ground truth” refers to information, conditions, or data that serves as the basis for a scenario being simulated or story being told. 

It represents a collection of detailed information about the situation or environment in which the game is taking place. Players enter this scenario-world at the start of game play. Ground truth is a key part of the world-building process that game designers use to create a compelling environment for players, whether in a Dungeons & Dragons campaign, military wargame, or video game.

Ground truth is crucial in gaming because it ensures that the simulation is realistic and relevant. It helps participants practice and make decisions based on the accurate detail, simulating real-world challenges and scenarios as closely as possible. Ground truth may include details like terrain, weather conditions, and the capabilities and locations of friendly and opposing forces. This information is used to create a scenario that closely mirrors the real-world situation, allowing players to train effectively and make decisions as if they were in the same situation in real life. In a world of fantasy that departs from real-world physics (i.e. the absence of gravity or the presence of magic), a ground truth tell players how they can interact in this new world. 

Having accurate ground truth is essential for the effectiveness of games and exercises as it helps participants develop the skills and decision-making abilities required for real world situations. 

Setting up ground truth in a game involves creating a foundation of accurate, real-world information and conditions that serve as the basis for the game’s simulated world. If you game uses a world of fiction, no problem! Your fantastic world just needs a set of fundamentals rules that players can understand and accept as true. 

Here are 7 steps to help you help you establish ground truth in your game: 

1. Define the Game Scenario. Determine the specific scenario, story, or context for your game. This could be a military simulation, a historical reenactment, or fantasy campaign. 

2. Gather Accurate Data. Collect accurate and up-to-date data related to your story. What details of your world might be important for your players to know, even if not immediately, as they interact in the game? This might include geographic information, historical records, or weather data. Here are some possible elements you might want to consider based on your scenario when building your world: 

• Communication Systems
• Conflicts
• Demographic Information
• Diplomatic State
• Documents
• Economic Data
• Energy Systems
• Food/Water Sources
• Geography
• Health/Medical
• History
• Labor
• Legal System/Laws
• Languages
• Military positions (friendly and enemy)
• Myths/Legends
• Non-player characters
• Political
• Professions
• Religion
• Services
• Settlements/Buildings
• Species
• Technology
• Terrain
• Time of Day
• Traditions
• Transportation
• Weather 

3. Create a Database. Organize the collected data into a database or structured format that the your game engine or human facilitators can easily access during game play. The data should be easy to find so that when the players inquiry about specific, they get a satisfying answer quickly. This will make the world feel very full and more realistic. 

4. Implement Realistic Models. Develop models and algorithms that use the data from the database to simulate how different elements in the game world behave. For example, in a tactical wargame, you’d use the terrain data to determine movement speeds, line of sight, and weather data to affect visibility and accuracy. In a role-playing game, the customs of non-player characters in a city may be relevant to your players campaign.

5. Establish Player Interaction. Allow players to interact with the game world based on your ground truth. This might involve controlling units, making decisions, or strategizing based on the information provided at specific points during the game. Consistency is key here! Players should have agency to move within your world but believe that the rules of your world are consistent and dependable. If they ask the same question twice, they should get the same answer twice. They will learn more about details from the ground truth as they explore your world.

6. Continuously Update Data. Keep the ground truth data updated to reflect changes in the scenario. As players make decisions, some ground truth details may change. This create the perception of player decisions have impact and amplifies the realism of your world. For example, you might update weather conditions or the locations of non-player characters as the game progresses. 

7. Test and Refine. Conduct playtesting to ensure that the details of your game world are realistic, challenging, and interesting. Make adjustments as needed to balance gameplay and realism to ensure that players can make informed decisions based on your ground truth structure.
