I find it fun trying to survive in a griefed environment in Minecraft, but it is tedious to create a new map, build lots of large buildings, half-tear them down, and then build thousands of tall towers out of random materials. Is there a world generator that can create griefed maps like this automatically?
No, there is no known map generator that will create a griefed style map. It's not impossible, but would require a very large effort to create the generator.
I would suggest going to the Minecraft forums and making a Request in the modding section. When you make your post, try to write out possible specifics for the generator.
- Style of buildings (Modern, Midevil, Asian, etc)
- Size of building (Width, Legnth, Height)
- Building material
- Style of grief (Random noise? General shape? etc.)
- Amount of grief (bits and pieces, whole chunks, etc)
Hopefully a modder will come along who's interested in helping. Things can then move forward from there. If there's no response there, try over at the Bukkit forums.
Hope this helps.
