I didn't mean resource trading at all. It will be a nightmare anyway, no matter what, because of our limited carrying capacity.
What I meant was trading items. Jordi said that we will be limited of how many recipes we can learn. So high level cratfmen will have different recipes. Let's say I want a weapon that the blacksmith of my tribe can't make. Or a pretty dress, since I'm a woman I'm willing to travel for hours to get it
I want to be able to run around and to pay for it when I find it. I don't want to pay with resources because it would be impossible to carry a big amount of resource there. Since the item is for me only, to fill my vanity, I won't ask my tribemates to run for hours to help me pay for it. If the price is another rare item I most likely won't have it so can't pay again.
That's why I said barter trading would kill the economy, not the resource trading, but the crafted item trading. The most fun of being a crafter is selling the crafted items to others....otherwise whats the point of it. You craft everything what your tribe needs then you can retire
The problem is that buying items from a crafter who lives far will be kind of impossible. That is stupid in a game which has heavy crafting and hundreds of different items.
I don't insist to have money. Give me any other solution which makes item trading possible and reasonably easy and I'll be happy with it.
