Roleplaying games are crazy.
As I look at my bookshelf now I see loads of books filled with rules; Pathfinder Core Rules alone has nearly 600 pages of the things! And yet us roleplayers don't bat an eyelid at them; we just seem to suck them up and then vom them out all over Internet forums to get one over some other loser that's also sucked them up with the same intent.
I play board games and bolt at the sign of a rules pamplet more than 6 sides, and yet I will happily wade though half a tree of rules for an RPG and long as they 'make sense' (whatever that means).
If IT books were as 'easy' to suck up I'd probably be darn sight better at my job!
