From the back of the box:
A fantasy role playing adventure game for use by a Gamemaster and any number of players (ages 12 and up). LANDS OF ADVENTURE includes all rules necessary for the creation of characters, encounters, combat, magic, and adventure. It is a unique game in that it has been designed for adaptability of world background.
Modular 'Culture Packs' detail the necessary changes and additions to the basic system to add on new 'worlds' from myth and legend. Each such world background is carefully researched and presents an in depth survey of the culture, religion, and social framework of the society portrayed.
This package comes complete with the basic rules to LANDS OF ADVENTURE and a double culture pack detailing the epic worlds of Mythic Greece and Medieval England (with an additional section on the England of King Arthur). Thus, even the basic game is playable in a world of the Gamemaster's creation or in either of the two cultural backgrounds provided.
