In this Medieval Mod version of CtP, tiles originally known as swamp tiles have been converted to tropical grassland tiles. Tropical grassland tiles are identical to grassland tiles, except for the goods they provide. They provide good homes for cities. <l:8,0>Farms<e>, <l:8,19>roads<e>, <l:8,3>mines,<e> and other tile improvements can be built with the same cost and benefits as on grassland. <l:6,25>Rivers<e> greatly enhance this terrain. The original swamp terrain was modified from its original game configuration to provide a more enjoyable and even-balanced game experience.
