OK, I won't beat around the bush - the Map Folios have taken a nosedive recently. First reason is that recently they tend to feature "in character" maps of countries/regions which have no landmark names but instead feature doodles of monsters, NPCs and locations.
They're cute. Obviously, somebody at Paizo HQ is going all giddy when he/she sees one and orders the next one right away. "Oh look, this tiny winy devil on the map of Cheliax, I want to pet him and hug him and call him George."
But there's a problem. They're not very useful in game. A boring plain normal map with city, river and mountain range names is ten times more useful. And a BLOODY DISTANCE SCALE. The Inner Sea Folio and its derivates (like the Shackles map) are AWESOME. Pure gold, maestro. These put the competition to shame. Please go back there.
The second problem is that the folios continue to be a part of the campaign setting subscription. This is illogical and frustrating, as I need to cancel my AP sub for the upcoming Ironfang Folio, as I fear that it will feature the same problem with a "cool in-character map full of tiny soldiers" map that will have me sigh and break out the Inner Sea Map Folio again.
