Hmm, a world without crime and war. Everybody would be vegetarian, the only animals left for dairy products and eggs would be treated nicely. Intelligence tests would be the major olympic discipline. Economy would shrink und only produce, what's completely necessary. The world would become a little bit boring, but everybody would like roleplaying and just imagine a more interesting world.
Warning: Human species may become extinct, because everybody would be timid and afraid of the other gender.
