So I gave it a crack - a stream and a road passing through undulating cultivated country. Here is the result:
|Terrain generation, using the method for an 8x8 square grid|
ignoring the outermost squares on this 10x10 grid except
for roads and rivers, and - potentially - railways.
Well: a bit sparse, but that can be remedied. That green shape is not part of Bob's scheme, but it occurred to me that one might add things like orchards, ponds/meres, swamps and enclosed fields. Requiring a 5 or 6 each for an orchard, pond or swamp, none appeared on this map. Allowing a 4, 5 or 6 for an enclosed field area, and using the system of location placed it where the green dot appears on the grid. Rolling a '5' for size yielded a 3-square area. I arranged it arbitrarily as shown on the map.
Pretty open terrain, possibly somewhere in the steppes of the Ukraine or the Donbas areas, in the locality of a State Farm.
Of course, I'm not going to let this map go to waste. I'll just have to think of a battle to fight on it!
