I'm working on a Role Playing Game source book with the idea that players take the roles in a world drastically changed, that old chestnut. The setting's a modern world where one day nearly ninety percent of one gender was change physically. Internal biology wise they are the same, but physically completly different. Think some kind of humaniod creature. It focuses on if women changed, but with opinions to play in a world where men were the ones that changed. Oh and the event that changed everyone also effected the animals and turned many into monsters, because why not. I know monsters would make some peoples day suck, but what about the change? How would that effect society as a whole? The tone of the book is actually a comedy, a rather black one at that. The plan is to have some satire of the hard science, dark and grim, "this is the real world, only worse" (read World Of Darkness, Traveler and many more). This plan includes almost explaining how did the change happen, only to get distracted and forget, censored or just contradict oneself. In summery: Need to know how the world would react if an entire gender changed physically into human monsters, have real monsters attack and keep things tongue in cheek about it.
