GURPS

What is GURPS?

GURPS (Generic Universal RolePlaying System) is a tabletop RPG designed to handle any setting, any genre, any level of realism. Created by Steve Jackson and first published in 1986, GURPS is the gold standard for simulationist RPGs — games where the rules try to model reality (or a specific fictional reality) as accurately as possible.

Where other systems are built for a specific genre, GURPS is built for everything. The core rulebook is genre-neutral, and dozens of supplements add rules for specific settings: GURPS Fantasy, GURPS Space, GURPS Horror, GURPS Cyberpunk, GURPS WWII, GURPS Supers, and many more. If you can imagine it, there’s probably a GURPS supplement for it.

The GURPS Philosophy

GURPS is built on the principle of internal consistency. The same core mechanics handle sword fights, gunfights, car chases, social engineering, and spaceship combat. The system is modular — the GM picks and chooses which rules to use, from the ultra-simple to the hyper-detailed.

This makes GURPS incredibly flexible but also potentially complex. A GURPS game can be as simple as “roll 3d6 under your skill” or as detailed as calculating bullet drop, windage, and armor penetration. The group decides how deep to go.

Why Play GURPS?

Universal: One system for every genre. Your medieval knight and your space marine use the same core mechanics.
Character depth: Point-based character creation with advantages, disadvantages, skills, and quirks. Every character is unique and detailed.
Realism: GURPS models reality with remarkable fidelity. Injuries matter, equipment has weight, and physics applies.
Massive library: Decades of supplements cover hundreds of settings and genres. The GURPS bibliography is enormous.

Core Mechanics

GURPS uses 3d6 under your skill. Every skill has a number (e.g., Sword-15). You roll 3d6 and try to get under your skill. Rolling 3 or 4 is a critical success. Rolling 17 or 18 is a critical failure. The bell curve of 3d6 means results cluster around 10-11, making every point of skill meaningful.

Characters are built with character points. You spend points on Attributes (ST, DX, IQ, HT), Skills, and Advantages. You gain points by taking Disadvantages (bad temper, missing limb, enemy, etc.). The point system ensures balanced characters and rewards creative flaw-taking.

Pro Tip

GURPS can be as simple or as complex as you want. For a lighter game, stick to the Basic Set and ignore the optional rules. For a gritty, detailed game, layer on the tactical combat and equipment rules. The system scales beautifully. Start simple and add complexity as you go.
