I am about to embark on building a Flash site with approximately 500 pages. The site is an interactive learning type of system, with about 10 "chapters" each containing around 50 "pages".

Each page has some sort of animation and interactivity, for example the user might have to decide whether a statement is true or false by clicking on one of two buttons, and then an appropriate response is displayed. The user can jump backwards and forwards between pages as they wish.

As far as I know, these are some of my options...

A) Build the entire site as a single Flash file with no external content.

B) Build each of the 10 chapters as a separate Flash file, and then have a master Flash file which loads in the chapters. Each page would then be a separate movie clip within the chapter file.

C) Build each indevidual page as a separate Flash file, and then have master Flash file which loads these in.

At the moment I'm thinking that option B would be best, and I'd be very grateful for your thoughts on this! Of course, there are probably other options that I haven't thought of.
