Terrain and Feature Adjacent Yields V 0.9
Terrain and Feature Adjacent Yields is a mod series to add bonus yields not only to the terrain types and features of a specific tile, but to the adjacent tiles as well.
Currently, in this version, only features add yields. These features are marshes, oases, and rainforests, which add +1 Food yields to neighboring tiles, and woods, which adds +1 Production to neighboring tiles.
These bonuses act the same as the adjacent yields of natural wonders, meaning they are additive. A tile surrounded by 6 marsh features would have a +6 bonus to Food yields. However, these bonuses disappear with the feature, so placing districts and certain improvements will remove the bonus.
