Something very important! I understand that gold is rare, and we cannot get more gold from trader, so I guess we could buy them with coins? But I guess coins system is quite far away to be implemented right now. Or we can get a shipment of gold, but a small one, like 10-20 gold, where a seed costs around that. This will not overbalance things, because you need around 30-15 shipments to buy a proper tech, which is a very long time. And what is the difference between oak and pine tree? I see oak tree, doesn't drop 2 seeds, always 1 seed, while pine drops 2?
