boats or canoe or somethin looks like it. Also I would like to see something about market plase. It should works like player manage how many people can be traders and wich resourse settelment wants to trade and wich kind of transport trader can use. People from my settelment takes things for trade and transport, and goes to other settelments. Some times later they back with other things like they have changed it in other settelemnts.

A more automated version of the market in later ages. You create a percentage of goods that go to the market and the trader trades with those goods instead of you having to manually do it all the time. Your villagers will buy new things based on what they can afford to trade and what they need to progress.
