[Suzerain of Sheol]

I suppose it depends if you count the spin-off novels for both series. Taking just the core books of each, WoT is probably longer, just by virtue of being 14 books long. Malazan has way more spin-offs, though.

On the myth thing, take an easy example: the death of Baldr, as we were discussing in the other thread. That story (particularly Hodr's part in it) had the potential to convey genuine emotion, but, what do we get? Odin conceiving a child with some random giantess to murder the poor guy in a callous dismissal of empathic, empathetic storytelling. As I said, though, that's not really what the whole myth thing was about. It's just not to my taste, 'tis all.
