This isn't your average campaign, but a template of map tricks. The rating is just one single score for the whole thing. It attempts to illustrate some map tricks, although they are fairly poorly executed. It has some basic tricks like trees in gaia buildings, bridges, a few cactus tricks etc, mainly from the map tricks articles. It isn't really necessary as you can see how to do them perfectly well in the map tricks articles and in any good campaign. You'd be better looking at those then downloading this template.
