From the publisher's website:
The huge success of the Fighting Fantasy gamebooks spawned, in 1989, a full-blown Roleplaying game based upon the same fantasy world. Originally published as three separate books, this classic game has now been revised, re-written and re-released for a new generation of gamers. Revised rules, brand new material and original illustrations combine to make this a classic RPG for the modern age.
The new version of Advanced Fighting Fantasy is perfect for original fans of the game, experienced roleplayers new to Fighting Fantasy and is ideal for those new to roleplaying.
Onwards to adventure!
