Ash's OpenTTD Maps
These are super old and I haven't looked at for a decade. But you obviously care about them or you wouldn't be here! So please enjoy.
Clontarf
A fictional, temperate bayside scenario with a diverse range of islands, rivers, and mountains. 512x512k map, based veeeeery loosely on the real life Clontarf.
Trislands
Three islands, with a relatively unique gameplay experience. An earlier scenario attempt.
Svalbard
After a passing fascination of with the island of Svalbard, I decided it would make an awesome OpenTTD map.
Having only a handful of settlements, I had to take some artistic liberty and appropriate town names from nautical maps, regions, and historical data, but it’s worth it when you create a transport empire spanning the map.
Fjordia
After Svalbard, I wanted to play with gouging realistic fjords into the mountainside.
While this map is sub-tropical and mostly desert, it still has some beautiful erosion and tectonic effects throughout.
It’s also sliced in three by a great river which makes water networks viable.
Bayside
Bayside is essentially a miniature continent, with industries further out, and an urban center along the coastline. Just a reasonably standard map, but nicely balanced.
Oceania
A concept map. Two large continents are separated by a vast ocean dotted with tiny islands. Transport goods on the mainland or set up a tourism network to the remote areas.
