I'm not really much of a fantasy reader but seeing that no hardcore fantasy fans seem to know the answer I'll try to help you out.I recommend... ok, don't laugh, read my post till the end... Nightwatch by Terry Pratchett.Yup, Pratchett.OK, his later Discworld novels from the “Vimes Cycle” are quite dark and gritty when compared to the pathetically small number of fantasy books I read so far (except for Sapkowski, of course). I think his books Carpe Jugulum, the recent Thud! and especially Nightwatch present a world somewhat similar to that of Sapkowski: dark, dirty, violent, and (to an extent) unjust.Alas, this stuff is more family friendly than Sapkowski's works, and the characters, even the protagonist, a noir-ish ex-alcoholic cop with street smarts named Vimes, turn out to be goody-do-gooders. There's a clear distinction between the good guys and the bad guys, but at least the bad guys are downright dirty in an interesting way and the good guys are not always spotless. They also seem to be somewhat more developed, Sapkowski likes to make (intentionally) underdeveloped minor characters, though morally less ambiguous Pratchett's creations are much more alive and individual.Humour is Pratchett's hallmark: in the books I mentioned he turns towards a darker variety of amusement (though still not as dark as Sapkowski).Most of his books have major themes; Carpe Jugulum is a werefolf story, Thud! is a parody of The Da Vinci Code, and Nightwatch reaks of fake revolutionary propaganda with a pinch of British kitchen-sink drama. Pratchett plays with established genres but his stories are heavier on the stylisation than those of Sapkowski. Expect lots of cliches being mercilessly poked at.If I were you I'd give Nightwatch a chance, I think it resembles Sapkowski most. There is some lore behind the DW universe but the core stories in Pratchett's books are independent from one another, so no worries there. And there's no unnecessary pathos (unless it's there for comical purposes). It's comic fantasy, but it amuses in a dark, witty and intelligent way.Anyway it's high culture compared to the generic fantasy tolkienesque foam and it's quite a good book by literary standards as well.Oh, and do get the original English version, just to be on the safe side, that book is a bitch to translate.
