Girl Interrupted:
Do the core GURPS Rules operate the same as Dungeon Fantasy? What is the primary difference?
There are a few rules changes for simplification, some equipment weights altered to line up with Low-Tech, over half the spells truncated from GURPS Magic... that's all very well codified in the
Dungeon Fantasy RolePlaying Game Powered By GURPS Boxset. If you prefer to delve into the much broader, not as trimmed down,
Dungeon Fantasy line, I also recommend picking up
Pyramid 3-60 Dungeon Fantasy III for the Wizardry Refined article, it adjusts spell prereqs and durations to work the way Sean Punch was envisioning, but didn't quite explain well in DF 1 Adventurers.
Or, what I prefer is to run using
DFRPG boxset with heaps of stuff swiped out of
DF added back in (and some stuff from Martial Arts).
