I'm not the biggest buyer of Paizo products ever but our table collectively has gone in for all 4 Bestiaries w/4 Pawn sets, 5 Full AP sets (two with pawns, maps, and card sets), CRBs & APGs for all table members, the Ultimate books (Magic, Combat, Equipment), many player companions, as well as a pile of minis. At this point, we're too financially invested to shrug our shoulders and walk away from the rule set.
On the other hand, I bought the ACG when it came out, and have the printing that reads 'Pathfinder Campaign Setting' on the cover. I dealt with the disappointment of getting a product with that error, figuring it was kind of fun actually. This errata release has invalidated a big chunk of the interior of a book with a misprinted cover, a book I paid full price for. Shall I ignore the errata, and if I do how will it effect the table's consumption of future Paizo products?
The first thing I did after getting the misprinted cover was to stop buying direct from Paizo. Now, my local hobby shop has lost out on my purchasing power as I go to outlet retailers like Amazon to save dollars on books that will likely be invalid by the time I get to use them.
I know this thread is more about specific issues with ACG mechanics, so I apologize for the possible derailment.
