I started reading Wheel of Time about 10 or 15 years ago. I think I stalled out somewhere around book 6 or 7. I love the richness of the world-building, and boy, I do agree with you on the detail (every culture had so much distinctive stuff associated with them, and there were so many of them!). But I really faltered because there were so many plot threads and characters that I got to the point where I couldn't keep them straight and everything seemed to be wandering in circles with no resolution in sight, so I quit reading.
