Twilight Shores
This is a map I made for myself. It is designed to take advantage of all 25 tiles so a mod is encourage but is not required.
There are ~130,000 trees so the map can support up to 120,000 more without mods.
Center square is the starting area.
It has a little bit of everything:
The buildable land is perfectly flat at an elevation of 200 to prevent flooding, except where it gets close to a cliffside or beach.
There are flattened areas near the water level for harbors.
There are entire map sections dedicated to each resource type; forestry, oil and ore.
There is a moutainous area to build on in the ore section as well as a secluded valley.
There are max connections of each type: road, rail, air and water
Each river is capable of supporting a hydroelectric dam for maximum output if placed at the river mouth.
