I have similar thoughts. I prefer to read medieval fantasy books, but after reading Era 1 I just had to see how the rest of everything played out. Plus it is brandon sanderson, so it has to be good.
I have read both Mistborn series, Elantris, Legion, Reckoners, White Sand 1, and Edgedancer. I'm currently reading Oathbringer. Edgedancer was probably my favorite of those; pancakes are amazing.
