1W gives
6 grassland
pig + corn
only 3 hills I can see, and I think low potential for any more.
1 sea tile (no huge deal there really)
1 floordplain.
You're missing one hill, the plains hill to the west.
Using my powers of hidden edge tile divination, I suspect there may be more desert or floodplains along the river to the north. If you study it carefully, you can see a few traces of what appears to be desert (red circle, 2N of the hut).
So, if that tile really is a floodplain, which one would expect since it's on a river, then 1W would give:
6 grassland
3 flatland forests (1 on grassland, other 2 are shrouded in fog)
pig + corn
1 plains tile
4 hills (one a plains hill)
2 floodplains (if my powers are to be trusted)
1 freshwater lake
1 coast tile
VS.
1SW1W
5 grasslands
4 flatland forest tiles (2 grassland, 2 in fog)
4 hills (one a plains hill + 2 more possible hills in fog to west)
Pig + corn
1 floodplain
1 freshwater lake
1 probable plains tile in SW corner of fat cross
So, other than the possible second floodplain, they are virtually equal. My only fear with 1SW1W is that the farther we move from our initial spot, the greater the possibility that we'll miss out on some hidden strategic resouces that were given by the map generator for our capital.
After much consideration, my vote goes for 1W. An extra floodplain is nothing to be scoffed at, and I've been burned too often because of moving.
Edit (as usual): Are we going to continue the game in this thread? Or did you intend to start a new one once we have our initial plans agreed and finalized?
