From the introduction:
Explore murky dungeons full of traps and obstacles. Battle vicious monsters. Cast spells and deal with evil magic. That is what this game is all about! Enjoying the pure escapist fun of pretending to do things that you normally would not and could not do in real life.
You will need: dice, paper, pencils, people, and creativity and imagination. Miniature figures, maps, building blocks, and other materials can be used to depict what is going on, but imagination is all one really needs to play.
