Customizing the materials used in creating the crystal ball village would be an enormous plus. I know that I can't be alone in adding different mods to make the game more difficult, and a few of those mods change how the villages generate too.
There's a necromancy mod that adds a graveyard and necromancer to villages.
A brew and ale mod that adds a brewery and (you guessed it) brewer.
And of course the glaring underground biomes mod you have to hunt unofficial version of. That one changes the materials of random generated buildings to custom stone types (different types of cobble to match the underground stones, all of which have different hardness, i.e granite vs soapstone).
Which is useful for natural protection against the tornadoes that eat wood villages for breakfast. Not to mention Mo'creatures ogres which go on rampages and break down walls when you sleep, or coro's zombie awareness hell that build up hordes and bust down your doors, ect, ect.
The thing is that the default village generated is just too weak. I could go mining and come back to the smoking remains of what was once my wife, child and buddy Frank.
There's this mod that generates cities/ruins/super dungeons that lets you (albeit not user friendly) edit the material types used to generate the structures to get different results. The .config file was massive and difficult, but was rewarding in seeing the crazy stuff the generator shot out. It would be super amazing if you could include something like that for this mod. I know you've done so much already but an initial user custom village, even if it was one safe building w/ a torch, would be like a legendary start in worlds bent on your destruction.
