Daranmon:
I have the RQG rulebook but haven't played it at all, so this will be interesting.
It's very close to RQII except...
there's a CHA stat for Charisma (which can go up or down between adventures based on a character's achievements
you have % affinity to element, power and (some) form runes
In order to cast a rune spell you first have to roll under the rune affinity of one or more runes that the spell relies on
In order to cast a spirit magic spell you first have to roll under POW*5 %
You get a chance to replenish rune points (used to cast spells) on weekly and seasonal Holy days of your cult (if you worship successfully)
There are some passions that try to kick 'bad' role players in the pants and make them play their roles
Barbeesta Gor, Maran Gor, Argan Argar, Odayla, and Kargzant-as-Yelm get a cult write up
