Overall, an excellent set of fantasy role-playing rules. It combines detail with simplicity. You have choices in combat (which is indeed perilous), yet it flows quickly from player to player, and is fairly quick overall. You also get interesting choices in developing your character as you gain experience. And you have a limited number of Fate/Fortune points for times when the dice are against you. Always nice to have the ability to avoid one bad die roll from ruining your whole gaming session. The Warhammer Fantasy world is, in my opinion, one of the better fantasy worlds available for gaming, though you need more than the core rules to see it all. While WFRP is not my favorite rules system, it is still one of the better systems I have played, and I wish Fantasy Flight still supported this 2nd edition to some extent.
On the negative side, I am not a big fan of the career system ... though it does work well enough so long as you do not have to "roll" for your first career. Note that I have a stong bias for game systems where you design a character you want to play, over coming up with a character using random rolls. To be fair, I do like the WFRP's career system better than the class/level system used in other games, however. While the insanity rules are interesting, I don't care for the fact that you gain an insanity point every time you take a critical hit ... and should you gain a malady from this, some of them could be fun, but some simply make your character unplayable.
The PDF itself is very nicely done. It would be nice if clicking on the TOC or Index entries took your to the relevant page ... especially considering how much the PDF cost. Considering that a new edition of WFRP is now out ... I have not played it as it is way to expensive to try ... the price of the 2nd edition books has now gone through the roof in response. I feel the cost of this PDF is a bit on the expensive side for an out of print, unsupported set of core rules. I was only able to justify the cost because this is one of the games our group activity plays.
Regardless,Warhammer Fantasy Role-playing 2nd ed. is system/world well worth a look.
