All i have to say is i run a game store and the Pathfinder core book is going to bring in allot of customers who have downloaded the free pdf. I am currently running a game every tuesday trying to get input from players and they all seem extreamly excited and are all willing to come in to buy the books the first week it comes out. People go into game stores to have fun and be around people who just want to play games if you give them a place like that they are more then willing to come to you for products.
