I voted Fantasy, or to be more precise, Glorantha.
I started my group on the RQ2 borderlands campaign. We're using RQ2 as the base as I wanted to show them Old School, after previously running some HeroQuest sessions.
As RQ2 is a little light on options, I have been picking out house rules from RQ3. This was beginning to become a headache, when trying to find anything to answer a query.
I was contemplating doing a kind of RQ2/3 summary for my players, when I heard about the new BRP book.
All the best rules from RQ, Stormbringer, CoC and Pendragon inside one cover.
Absolutely brilliant!
From now on, all my RQ Glorantha based games, will be based on BRP.
Loving the book.
