W8. No charterstones stage, but Venetian market was set. Dangerous travels, hardness to transport the stuff, the value of the items that was being sold was quite high (since no-one else could afford trading)

W9. Charterstones + Portico update, before backracks and composts. Travel is cheaper now and safer, payment variety is the same as in previous worlds (barterstands limitations), slightly more items being sold (such as raw materials, metals and etc.), value of items was quite low since everyone had pretty much the same quality of items.

Current situation. For dynamic trades there should be more valuable items that could be sold, ease the transportation and fix the barters limitations.
