How a masterplan works
方式01
A real reference
Every new line starts from a real place — a prefecture, a station, a river valley — pinned in the Atlas.
02
A written ruleset
Station spacing, road hierarchy and zoning limits, fixed before the first road.
03
Documented stops
Each episode gets notes, chapters, mods used and before/after numbers on this site.
04
Open save files
Patreon members download the save at every milestone and build alongside.
