Yeah, I bought the softcover MOSW, and MOROJ is thicker. It'll take some time, but that's cool. I've been reading YBY a year at a time, out of order just because, so eventually I'll finish that one, too.
ROTJ is the same page count as ESB, 372. I'm chiefly glad I didn't buy it for 3 times as much in hardcover.
YbY really is a flip-through type book, I read a few pages in and it's a bit dry as a straight read.
