With default generation, NPC villages can range from 7 buildings, to 26 buildings.
The mean tends to be around 13 various buildings.
No.
you can get it from npc villages. here is a seed for a npc village: FINAL
You build your own house and you can find NPC villages in the world
There are no cities in Minecraft as of yet, only NPC villages which spawn naturally in the game world; cities must be built by the player(s) of Minecraft.
There are randomly generated houses in 1.8 that are part of NPC (Non-player character) Villages. These will contain NPC Villages once 1.9 Beta is released. 1.9 has currently got a pre-release available for download, so NPC villagers appear in that.
No not yet. There will be once its updated though
I'd say a Desert or Plains. NPC Villages are good for a starter home, and provide materials as well!
You can't make villagers without mods. They spawn naturally in so-called NPC villages randomly placed on the map.
If you mean generated structures such as abandoned mineshafts, NPC villages, and strongholds, than these cannot be found in the game yet, and can only be found in the PC version of Minecraft.
Ok this is Minecraft not maths, In alpha you cant actually gat unlimited torches, and... you are still using alpha?!?! why don't you update to Minecraft beta 1.9pre, it's awsome with snowmans, pistons, wolves, and NPC and NPC villages, just click the force update button on the launcher.
A Minecraft world seed is what Minecraft uses to generate the terrain to begin with, it does not create any user-created structures like castles, only things like NPC villages, mines and strongholds.
You can find it in NPC villages or underground dungeons. But the easiest way to get it is to mind regular smooth stone, because that produces a block of cobblestone.
