I was just wondering how many people, given BRP's flexibility, have built extentions for the rules outside the basic core. These could be, like the Eldritch Hooror extention, minute changes, to say a full blown world setting.
Also, I was wondering what system most people play when using BRP. Is it the classics, like Runequest, Superworld, Elfquest, or CoC? Perhaps it's of your own invention. I'm just curious to know.
