About this Mod

New:Sim-U-Kraft
New:Sim-U-Kraft is a city-building and NPC life simulation mod for Minecraft. It lets you
found a city, claim land, place buildings, hire citizens, and turn a simple settlement into
a working town with construction, farming, commerce, industry, and logistics.
The mod is available for Minecraft 1.21.1 on NeoForge and also supports
Minecraft 1.20.1 on Forge.
Installation Guide
Download the file that matches your Minecraft version and mod loader. Use the NeoForge
build for Minecraft 1.21.1, or the Forge build for Minecraft 1.20.1.
Once the correct loader is installed, place New: Sim-U-Kraft into your mods folder. You
also need the matching version of LDLib / LDLib2 for your Minecraft version.
Gameplay
Start by placing a City Core to create your city. From there, you can claim chunks, manage
city funds, and begin growing a population of citizen NPCs.
Buildings are selected through the Build Box. Choose a building, preview it in the world,
confirm the placement, and let hired builders gather materials and construct it.
Citizens can take on different jobs such as builder, planner, farmer, commercial worker,
industrial worker, and logistics worker. Over time, your city can grow from a small base
into a living production network with homes, farms, shops, factories, warehouses, and item
routes.
