I also read Ready Player One this year and thought it was excellent. Since then I've been searching for more books that pull me in like that one did. Way of Kings is pretty good so far.
Reminds me of House of Leaves (Danielewski), which employs typography and layered (fictional) authors in a very compelling and unique manner. I can't imagine ever reading another book like that though (although I know I'll enjoy rereading it in the future). Any copy-cat would seem like cheap clone compared to the original.
