One of the things that distinguishes GURPS from other RPGs is that GURPS allows gamers to play with a variety of degrees of granularity. It is possible to run a game that requires players to track lots of details, but it is equally possible to run a game that focuses on a couple of core skills with generic difficulty modifiers. The key to making GURPS accessible is remembering to limit the decision-making so that all the decisions are interesting.
The Granularity Spectrum
To visualize this idea, imagine a spectrum of granularity. At one extreme of the spectrum, there are almost no details to track: the characters have the four basic attributes, a handful of skills, and the game exclusively uses generic task difficulty modifiers. This end of the spectrum doesn’t require many decisions: character creation is straightforward, there aren’t a ton of mechanical options to consider in play, and most of those mechanical decisions will be blunt choices along the lines of “I choose to attack” or “I choose to run away.”
At the other end of the spectrum, play can revolve around a myriad of complicating factors: choosing between skills with shades of differences (like Physician vs Diagnosis) after factoring in situational modifiers, defaults, talents, and the like. At this level, players can be required to make decisions about how to manage the number of bullets they are carrying, their exact positioning on a tactical grid, etc.
Neither extreme is necessarily right or wrong. The key factor is whether the decisions are interesting. In other words, are there compelling consequences to the decisions so that the players are invested in what they decide?
The extreme granularity may be too overwhelming for a new player who doesn’t understand enough about the options to make intelligent choices about the options available. Having to make all those decisions isn’t interesting—it’s burdensome. The significance of the options is lost if the players are struggling to keep up with the available options.
Conversely, the less detailed extreme may gloss over too many decisions for a more experienced gamer, leading to boredom and a lack of strategic choices. The game may be less fun because there aren’t enough decisions to keep the players engaged, and the decisions that are available are at too high a level of abstraction to be meaningful.
Choosing Your Game’s Granularity
When deciding how to run a game, the GM and players should decide what level of granularity they want in order to encourage interesting decisions without being overwhelming. If the players are less experienced or have less knowledge of the system, they may not be able to take advantage of the decisions available under more granular options. If the gamers want to run a lighter game, rules-heavy options will be cumbersome. If the participants enjoy detailed resource management, more granular games may offer them opportunities to make more interesting choices.
Remember that granularity is not all-or-nothing. In fact, one of the things GURPS does really well is creating a self-consistent gaming system. You can easily choose to use very detailed rules for one element of the game and use less detailed rules for other elements. If you want to have tons of combat detail but treat social interactions as a generic Persuasion skill, you can. If you want to get into tons of detail for planning and strategizing how to pull off a heist, but leave the details of getting the job vague, it’s doable. Almost any subsystem of the game—powers, magic, social interaction, combat, starting the adventure, travel, healing, after-encounter cleanup—can be treated with extreme detail, or simplified with a single dice roll or even narrated without dice.
Adjust Granularity on the Fly
Because GURPS is a consistent system, you can adjust the granularity on the fly. If your players are overwhelmed by the number of decisions they need to make, simplify things! Use skill checks with task difficulty modifiers rather than digging into techniques or situational modifiers, stop tracking encumbrance or fatigue, and restrict the combat options available.
Conversely, when your players start to feel that the game is too simplistic, turn up the granularity so they have to face more tradeoffs. Introduce penalties for specific techniques, lack of familiarity, or equipment quality; track their encumbrance and require fatigue points for pushing their limits. Expand the combat rules in play and start having the NPCs make smart tactical decisions so your players need to up their tactical game.
By starting simple and gradually adding in granularity in order to keep the players engaged, you can keep the game accessible and fun. When the decisions are interesting, so is the game!
