Stardock should provide a basic PDF manual with the game, but then offer other hardcopy types available for sale. These hardcopy types would naturally provide more than the basic PDF manual. Here are some examples:
1} Basic PDF manual copy... comes with the game and occassionally updated with patches.
----Now for the HardCopy examples----
2) Advanced HardCopy of the Manual (Stardock chooses the price)... includes:
A} Extra pages on the myths behind one or more creatures... not found in the PDF manual.
B} Listing of HighScores and Rankings amongst all the Stardock Developers for games such as GalCiv_2, Civilization_4, Worms:Armagedon, Elemental Final_Beta version, etc., etc.,
3) Collectors Manual (Stardock chooses the price)... includes :
A} All the same features as found within the Advanced HardCopy
B} Plus actual signatures from the entire team at Stardock who worked on Elemental
C} Golden Ticket to join a group chat session with the developers during the middle of 2010. Only those with golden tickets will be allowed to join this group chat session.
... If you build it... they will come.
