New:Sim-U-Kraft

This mod is a reset/update version from 1.7.10, with optimizations to the original logic.

You start with only $20 in starting funds.
First, you need to craft a City Core.
Open the Core to create a city.
Then craft a Construction Box.
Hire an NPC.
Choose what you want to do —
Select a building type or planning type.
Then start building and planning.
You can combine a book with the NSUK Construction Box to craft a guide that will instruct you.

If you prefer a more concise or alternative phrasing, let me know.
