I only recently started reading Brandon Sanderson, but I've read 10 of his books since Labor Day (Elantris, Warbreaker, all Mistborn books except for Band of Mourning, which is coming from Amazon as we speak, both SA books, & Arcanum Unbounded) and really enjoyed them. Words of Radiance is probably my favorite of his books, and I really love how the Stormlight Archive books are done in general.
I've been lurking a bit in the Stormlight Archive section because the theorizing reminds me of my time on Westeros.org back in the day, and because I want to get a handle on what I missed in my initial read-through before Oathbringer comes out. I know a bit about the Cosmere, but there is a lot there that I'm still putting together. I really enjoy that kind of storytelling, and just knowing that there are connections between the different worlds added to my enjoyment of the books.
