This early universal rules set by Chaosium uses the Basic Role Playing (BRP) rules and contains three worldbooks: Fantasy World, Super World, and Future World.
"* Magic World: Meet magicians, warriors, rogues, and sages in Magic World. Often treasures found here bring high prices on the Wonder city market. Quests will be scheduled upon application. Some skill at arms is advised before entering this world. Magic World caves typically are crammed with life: spelunkers and explorers beware.
* Superworld: You'll be stronger, tougher, and have special powers in Superworld. If you step in front of a lightning bolt, or get trapped inside an atomic pile, or drink the wrong test tube, for superheroes are hard to kill. No foreign languages to learn; all transactions in U.S. dollars. Have a soda, smash a supervillain - everything is great in Superworld!
* Future World: Thousands of years in the future, the galaxy beckons. Beyond the Empire's edge endless stars await. Get a booster shot, check your blaster, renew your passport - then stroll into Sauriki plots, corporate wars, pirate inventions, and the thrill of unknown worlds. Xenophobe adventurers should proceed with care."
