At a certain point in my life, I assumed that I was pretty well done with OBSESSIVELY nerding out over things. Don't get me wrong, I still get really into an excellent movie or TV show...but just not in the same way that I used to, you know? Not in that scouring the internet for tidbits, reading every last drop of an author's work, memorizing names and places kind of way. That's why Brandon Sanderson has been such a blessing for me. His incredible writing and beautiful world building has rekindled a childlike sense of nerdy obsession in me. I had forgotten what I was missing until I cracked open Mistborn, and my headfirst dive into the Cosmere began. I feel like I'll never know everything there is to now, which-based on his prolific output, is a very real possibility!
Here's my personal definitive ranking:
Stormlight Archive
Mistborn: Wax and Wayne
Mistborn (Original Trilogy)
Emporer's Soul (my favorite short story he's ever done, by a country mile)
The Rithmatist
Reckoners Trilogy
Alcatraz and the Evil Librarians Series
Legion/Legion: Skin Deep
Warbreaker
Elantris
