Gritty fantasy like Joe Abercrombie

My favorite author is Joe Abercrombie, and I have read all his work several times. The original First Law trilogy are my favorite books.

What other series can you recommend for the same style of dark, gritty fantasy, complex characters, and engaging storytelling?

I have already read and enjoyed A Song of Ice and Fire, The Faithful and the Fallen, The Poppy War, Red Rising.
