Your opinion on 'The Rules' ?

Zoe
For the ladies who have read the book 'The Rules' (or variations of it) what were your opinions of it? Basically the book(s) give you a set of rules to follow in order to 'get the guy'.
I've read it and it intrigues me, but I don't agree with everything the book says, like CONSTANTLY playing hard to get to make him be on his best behaviour.
Anyone 'broken' the rules and still find themselves in healthy relationships?
