This is where Paizo beats WoTC into the dirt. Their adventure path series and individual adventurers insure that when people do play, they have a wide variety of material to play with. WoTC seems bound and determined that if it's not going to be a big seller to avoid it at all cost. For those who point that the APs and other material from Paizo are huge railroads, you have not been paying the same attention to the offerings of the DDI which are, in my opinion, much worse in many regards including their basic encounter encounter encounter set up.
