About New_civilians's terrain : I'm sorry but I don't find these very good
The idea of using a road in center, to split the fields in 4, is completely different from what the original farm did, so they don't "meld" well together.
Also, tactically, they don't seem like very interesting terrains. There are very few things more than 1x1 to block line of sight, and so many axes of symmetry that the terrains behave the same, no matter how they are arranged together.
IMO, extra "farm" blocks could include :
- cattle shelters and work cabins : small (3-5 tiles wide), with no door, because an entire wall is open. These are always dangerous places to approach then safe to hide in.
- In the fields, packed hay should be where the tall grass has been cut. Good opportunity for assymetry, and if the packed hay is close to the east or south borders, climbing on them may allow peeking - a lot of farm blocks have a hedge on north and west.
- Large pile of
dung dirt could be used as a minor spot of elevation (1 level high, 4x4 or 6x6). Always interesting to hide behind or climb on top.
edit: I tried with MapView, there are really few tiles in CULTIVAT and FARM :/
Here are two blocks which illustrate what I meant : the partially cropped field on left (mostly for flavor, the packed hay is really not tall), and a cattle shelter on right.
