As the name suggest this FN map has not only a river running through it but also has roads or tracks.  The random generator doe not always connect the Town Centers to the river. It does however connect the town centers to each other, sometimes by road,  and sometimes by river and road.  It is possible to be connected but not to be able to gain access to your allies due to crossing places being blocked by trees.   The worst thing about this map is that the generator does not always keep allies and enemies on each side of the river.  This can be made even worse by the fact that you may just be a short walk down the road from your enemy and find yourself being rushed by a villager attack.  The map above shows the teams as they were generated for a particular game. Blue and yellow show allies and enemies respectively.

There are some places to cross the river but you may have to cut the trees away to do this. Shore fish are plentiful if you can get to them, you may have to waste time trying to cut wood to gain access to the water.  If you do however end up close to the water and can fish then you will have a massive advantage over your enemies. I think this map has the potential to speed up the game and to make trading much easier. Could be very interesting once it gets going but due to the random problem of not a;ways being allied together means this map is probably a no go for many players.  It may be possible to correct this problem by remaking the map in the form of a michi map.
