Unlike much of the human-readable stuff in the playfield files, I can't quite grasp what is going on here. What do they do? What are their implications on biomes and POIs? How do they "play nice" with each other? Also, any suggestions on how I might configure a simplistic playfield so that I can experience their basic form? Lastly, if these are already described somewhere on the forums and I missed them then please feel free to chastise me (and kindly post a link). Thanks to all you fine folk!
