Wow, the new PDF is
huge! I guess it has high-quality graphics. This is nice, but unnecessary and even bad for ereaders; I don't even want to try loading it on mine.
Here is a way to shrink PDFs considerably (uses
Ghostscript, free and available for the major platforms):
gs -sDEVICE=pdfwrite -dPDFSETTINGS=/screen -dProcessColorModel=/DeviceGray -r170 -dNOPAUSE -dBATCH -sOutputFile=mag_small.pdf Mistborn_Adventure_Game-v2.pdf
Note that
-r170 sets the target resolution to 170dpi; adjust that to suit your display and needs.
This shrinks the 70MB file down to 11MB. The command can run a long time, be prepared.
