This set of tiles has a very particular application. Since this is e-Tiles after all, there's probably two tactical uses: defending a friendly temple or invading an evil one. If you're interested in defending a good-aligned temple, which is what I used for one of the first Freeport scenarios, the tiles have a red gear-like "law" feel to them, complete with gear covered pews, a giant red gear-patterned rug, and even a gear as an altar. This is unfortunately a little too lawful and not enough good in my opinion. There are two alternate altars that are generic enough, but they don't have the oomph that the red lawful motif brings.
The other tiles have hammers and a forge, clearly for dwarven worshippers. Unlike the law motif, there are no hammer-themed pews, but perhaps that's for the best. Unlike the law motif, the hammer motif could be used for evil or good dwarves so there's more incentive to use them.
But the real centerpiece of this set is the snake altar. Freeport and Call of Cthulhu campaigns frequently feature temples worshiping Yig and this set features a serpent-encircled altar, a 20-foot diameter pool surrounded by interlinked serpents, and a serpent design between two corner columns.
With all these sets the most important feature is its utility to your campaign. There are some unusual choices here -- law, dwarves, and snakes are not what I would consider to be typical temples that would be either invaded or defended – but if you have a campaign featuring any of those temples then these tiles will do nicely.
