Also, Paul T, “the GURPS game you are being invited to play” is a somewhat different beast than “GURPS,” with a different spot on the chart, almost certainly moving up the specificity axis (and possibly but less likely, the narrative-awareness axis). Same as Burning Empires is in a different spot from Burning Wheel, or Eberron from D&D.

In fact, if there are rules components being added or subtracted for setting/theme purposes, it’s probably gaining in both setting and procedural specificity.
