Well, judging from the published Flip Mats that have a direct connection to existing AP, these were less useful than generic ones for me. The Fall of Plaguestone is the best example, one of the few maps I didn't buy. About the four Play Testing maps I had mixed feelings.
Anyway, I'll see how these new maps come out. Just wanted to say that not all costumers here play published adventures - I don't even play Pathfinder nor DnD.
