This is the 24th release of ZZTong-Prefabs. It marks a major milestone in that it delivers 200 POIs and 50 Tiles, plus 24 is my lucky number. A great many people have supported me through this extended effort. In particular, Stallionsden of CompoPack fame, has kept me aware of developments in POI tools and techniques, plus provided advice when needed, especially when I was getting started. My goal has remained unchanged throughout this effort -- address issues related to world variety -- with POIs of an acceptable quality. In short, I'm in the "volume" business. TFP (and others) have the "quality" business covered.
