The rules were a bit too prominent. More fluff would have been better, and the art could be better as well (especially in light of today's 3D programs, but the book was written in 2000 or 2001 I believe).
What really gets on my nerves though is the sheer size of the PDF. It's over 150 MB I think, and it is a pain to read or even flip through since it slows down to a crawl/lags terribly even on very good computers with 2 GB ram and dual core processors. That was very, very sloppy work.
We're running a game where sex comes up often, but the actual act is handled "off screen", and the rest often in an abstract way (After perform and bluff checks: "You impress the Duke with tales from your adventures, and your skill at dancing, and manage to seduce him. After an hour of flirting at the party you two retire to his bedroom for more. Do you want to persuade him to give you the ring you seek as a gift, or simply wait until he falls asleep and then steal it?")
There are situations where we go into more details, but even that stays "clean" ("Ok, you had some fun with the kinky drow in her "chamber of fun". Flip a coin, you've got a 50% chance that you're tied up right at the moment the baron's men storm inside to arrest you for questioning regarding the fate of the baron's missing heirloom").
Personally, sex is such a driving force for many people (see all the sex scandals in politics), I do think there's a lot of stuff that can be used in a RPG, as plot hooks, character background, campaign background etc. Most does not need any rules other than "use bluff for seducing" and similar stuff though.
