No joke here. I just think stuff like this is interesting.
I got into the series very late, like SA: 4 was out - so I'm still catching up through all of his previous works. I just finished Mistborn era 1 (I think, I don't know where era 2 starts but I'm assuming it's post-Harmony). There's just something about Stormlight Archives though, it tickles me in a way Mistborn has not (not to say I disliked them, I just fucking love Kaladin).
