I have just mapped Ma'Spa centred on the spawn, and labelled all the places I know about upon it (and one or two I discovered during the course of my cartography).
Kind of gives us an idea of what's out there and how spread out it all is.
I'm kind of seeing a main north-south line and a main east-west line, which could pick out most stuff there.
If anyone has anything I've missed (especially if they want it on the train line), please say.
That corner of Genesis looks pretty obscure; there are pumpkins and clay there, both of which were rather rare back in the day, so I'm guessing it's the middle of nowhere. I've no idea how much of the empty land around Genesis Havoc carried over, though.
It might be cool if those who wish get the chance to design their own stations in the areas around their properties...
