This is s site that I love: http://www.ffproject.com/ check it out!

Here is how it presents itself:
"For the benefit of those who've never heard of them, Fighting Fantasy Gamebooks would consist of around 400 short numbered passages of text. Typically they would tell a Tolkein-like story, but the reader / player would be given options as to how they wanted the story to develop. This involved presenting a choice of numbered passages to read next.

There were also other rules, generally to do with rolling dice at appropriate moments: to determine the outcomes of fights, or the performance of difficult physical feats.

As a kid, I read several Fighting Fantasy Gamebooks. Many years later, while teaching myself CGI programming, I remembered them and felt that Fighting Fantasy would make an interesting subject to practice on. As a programming exercise, I wrote the software featured on this website.

The idea is that the software should be able to drive any Fighting Fantasy Gamebook, so long as the rules don't deviate too far from the basic system. It's just a question of adapting the books into the correct format. I have done this with several amateur gamebooks, this website is the result. "
