Very specialized, which isn't surprising, but also very good. The temples are all well depicted and the sacrifice temple is good enough that I'd almost be happy with just that. The cultist warehouse is nigh perfect and I really, really like the healing temple. Those three alone gave me more than my money's worth.
The druidic mountaintop is dull but there's only so much that you can do with a circle of standing stones. The spider cavern is compact but great for any small, underground shrine, temple, or sacrificial site.

I'm really looking forward to using this one.

I was also dissapointed by the Sewers pack, but was glad to see that this one is back up to the quality of previous packs.

I'll be using the Spider temple for the Throne room in Savage Tide's 'Here be Monsters' (with the spider image covered up), and the Healing temple for Farshores's temple in 'Tides of Dread.' I'll be trying to figure out a use for the sacrifice chamber and warehouse, which are very nice as well.

Map Pack: Temples is very creative and usable for specific situations. For example, in the Map Pack: Temples pack, there is a fantastic HEALING TEMPLE that will have great use as well as a very-well done CULTIST WAREHOUSE and SPIDER GOD CAVERN. And there's even a place for Druids and a scary chamber for sacrifices!

The maps fit together easily and creatively!
