This is an evolution of the ideas we have discussed before, starting from contract shipping. We made a real effort to proceed with contract shipping but the way trade is conducted, makes it uneasy. Even the follow up ideas about it were still problematic with a lot of... bureaucracy.
Besides the selling part, the warehouse capacity limits can now be flagged as implemented. Percentage would be awkward as both players and the server would have to spend some extra time calculating every time. Percentages will work better for plantation acres distribution though, as we have discussed elsewhere.
This will open at a new players market. It will have its own page and different interface than any of the markets we have today. I am currently testing it.
This will be player to player market directly. So cards that affect the port market will not affect these trades.
We thought to put some of the technologies as prerequisites but I think that such a feature should be available to everyone in order to work at its best. So this has been omitted.
