Abstract

Problem: How well does the GURPS tabletop RPG system translate into a computer RPG, and what challenges arise during implementation?

Approach: Tim Cain draws on his firsthand experience implementing GURPS for the original Fallout before the license was lost and replaced with the SPECIAL system.

Findings: GURPS was exceptionally well-structured for programming — its rules read like switch statements and its skills, advantages, and disadvantages were cleanly defined. However, critical problems emerged: the system was obscure to most players, combat pacing was lethally abrupt (fine → dead with no warning curve), extension-dependent features like magic required unique code, and many skills (e.g., Animal Handling) had no clear computer analogue without a human GM to interpret edge cases.

Key insight: A tabletop system designed with logical rigor is a joy to code but may still fail as a CRPG because computers cannot replicate the interpretive flexibility of a human game master — the very thing that makes tabletop RPGs work.
