Actually, challenges, to be precise.
Challenge one is the RPG Owlbear: you take subsystems from different gaming systems and slap them together to create a monstosity of a system that is as dorky and ungainly as, well, an owlbear! For example, you might use the hit location system from Twilight 2000, the magic system from 1st edition Runequest, the gun combat rules from d20 Modern, and the penis size rules from FATAL to make your dream 1860s Western game!
Challenge two is Adventure! For those of you who don't visit RPG.net, Adventure is a pretty good game designed for pulp settings. The goal of this challenge is to use it for the most inappropriate setting you can think of -- something as un-pulp as you can imagine. Like 2001: A Space Odyssey. It just screams pulp, doesn't it? :heh:
Take either challenge or both! Everyone who takes the challenge is a winner because, somewhere, you know King Stannis will be twitching with rage. And he likes that sort of thing. :deviousgrin:
