Creates large procedurally generated cities in your world for you to explore. Cities are based on a customizable format that lets you customize many aspects such as materials, size, density, and rarity to your desire. Cities also include custom wall styles, buildings, and dungeons to conquer. Currently eight city styles come with the mod, including friendly cities inhabited by villagers, several “ruined” city styles filled with hostile mobs, cities in giant underground caverns, and a city that spawns only in the nether. SSP and vanilla SMP versions are available.
