Someone asked me about an (old) GURPS calculation today, and I was thinking that many rules changed in my years playing GURPS.
Here is a tiny handful.
Back in my day . . .
. . . Block was 1/3 of your Shield skill, because Block at 1/2 Shield skill was deemed too effective.
. . . Karate did impaling damage to the vitals!
. . . Head was one location, not two. And then it was Brain and Head, not Skull and Face.
. . . there was no limit to Shock penalties.
. . . Stats cost 10/10/10/15/15/20/20/25/25 (and so on)
. . . you could stack up enough PD (which is also gone, good riddance) that defending wasn't necessary to defend.
How about you? No cheating by peeking in the books. Just from memory, what's changed since you started playing?
This one is GURPS - non-GURPS players feel free to steal this topic.
