Sorry if this is a silly question, but I think I heard mention of the Hiergamenon being in game as an encyclopedia somewhere?  Is the limited edition version just the same thing printed?  Or are there differences between the two?  I like the idea of it, but am having a hard time justifying the extra $40 to buy and ship the limited edition over just digital download.  

Also, on a semi-related note, any idea why companies don't seem to offer multiple shipping options anymore?
