Blood Sword

This game book series distinguishes itself from the other mainstream game books in various ways, adding up to the complexity of the rules and providing a combat system that is very similar to the miniatures combat system as used for instance in "Heroquest". Whenever there is a fight, a map is provided showing where the players and their foes are located, and players must resolve the fight using counters or miniatures.
The series supports up to four players; a single person may play with a powerful character, or a team of four people may play with a diversified group of less powerful characters (a Warrior, an Enchanter, a Sage and a Trickster). When multiple players participate, a single person is designated as the reader, and he or she must read the book aloud to the group; however, at certain points, different characters have to read sections to themselves privately, giving different knowledge to different people.
