The biggest weakness of most of 0onegames' battlemaps is their lack of portability. The dwarf temple from Dungeon Rooms IV, for instance can be converted into a temple to darkness by the simple expedient of placing a large, circularly based demon minature over the dwarf, but it's still a temple and will only see use in the adventures where a temple is appropriate. And other maps are more limited. The tree of life from that same set is not likely to see a lot of use in any of my games.
The City Shops floorplans doesn't suffer from that weakness. I'm almost guaranteed to need a tavern map in every campaign I run--sooner or later, there will be a bar fight. Similarly, a stable map will be consistently useful. The shops are all fairly iconic and can be cut out and placed down on a larger map to make a fairly convincing city street. All of the maps have a good level of detail and would make interesting terrain.
There is still a little room for improvement, however. First, since these maps are best used in the context of a larger environment, it would be nice to have exterior walls and doorsteps included in the pdfs. That would enable a more convincing cluster of shops and would enable their use as parts of a village scene. The second improvement would be to give some of the shops a second story or at least a stairway going up. Since many fantasy towns resemble european villages and cities, multistory buildings should be more common than sinlge-story ones.Rating: [4 of 5 Stars!]
