From the back of the book: "Bangkok is the first adventure/campaign sourcebook written especially for the revised Twilight:2000 game system. It presents players and referees with a totally new and different background against which to adventure: Thailand. Bangkok describes the geography, climate, peoples, and culture of Thailand, giving maps of the major cities, a rundown of the three main political factions, and complete organizational details of the various armies. From the opium warlords of the Golden Triangle to the "sea gypsies" of the Gulf of Thailand, from the primitive hill tribes of the northeast to the sophisticated mercantile/criminal syndicates of Bangkok itself, each region of the country is fully described. Each section also includes a short folio-type adventure set in that part of the country.
Further chapters provide adaptations to the slightly different milieu of Merc: 2000, enabling Bangkok to be used with campaigns for that system as well. IN all, Bangkok will serve as a stepping stone to a whole new world of exotic adventures in the Twilight: 2000/Merc: 2000 roleplaying universe.
