This mod adds a spawn system for animals, as well as a wolf unit which takes advantage of that system.
With this system, based on the code Firaxis did for Civilization IV animals, animals can spawn on their native terrains and features: the wolf which is included in this mod can spawn in forests and (unfeatured) tundra and snow. Animals do not spawn in tiles already owned by a player.
A new game define value, "UNOWNED_TILES_PER_GAME_ANIMAL", controls the quantity of animals spawned: a higher value means less animals spawned, while a lower one means more animals spawned. The lowest value that "UNOWNED_TILES_PER_GAME_ANIMAL" should be set to is 1.
