A big update
One more resource, food.
Upgraded settlements consist of several tiles.
The upgrade requires time, but you can speed up it, spending 'power' resource.
A new category, goods, appears. They are especial resources, which can be found on map (salt, marble, ore etc).
You can deliver marble from a career to a settlement.
You can transfer goods from one settlement to another, creating trade routs.
The settlements with access to marble are upgraded two times faster.
