Oh yeah, because graphomania is awesome.
I dont know how the devs imgine the game's trading system in the future, but personally I imagined it as peddlers traveling between villages with carts loaded with trade goods, trading at each village and going on to the next one.
With object quality and multiple metals implemented, there is now no problem with lack of tradeable goods. There are so many goods that you can be sure there will always be demand for many kinds of decent quality goods at any village. But at the moment you wont see any traders going between villages, of course there are many reasons for that, so ill try to think of some ways to make the more realistic trading system more viable.
1) No teleports to RoB.
At the moment, the teleport is okay because the trading system is not ready yet, and trading by teleporting to RoB from your village and trading there is probably the only way to effectively trade at all. But once people can easily initiate trade with villages, the RoB teleport will greatly impede that kind of trading. The main reason is alt exploitation. Atm its quite common to have alts at the location of high quality soil/water/sand/clay, basically dropping their price to minimum, because you can always easily get more of it for free using your alt. Remove the RoB teleport, and that wont be possible anymore, even the most noobish traders will have goods to trade - they will be able to go to a place with high quality natural resource, collect it, and bring it so some faraway village. And people there will be happy to buy it because its much easier for them than to walk to that place themselves.
J&L have given a small hint about their plans on teleportation and stuff, and i believe if that teleportation debuff they have mentioned will be enough to eliminate the alt abuse to gather high quality resources, then its okay.
2) A bell.
Yes, a belltower with large bronze bell anyone can ring, which would work as a way to alert the villagers of your presence. This is actually VERY important, because finding people in a village is quite bothersome, especially if u have a cart behind you. Currently, the only way to do it is through metagaming, such as IRC. Being able to alert the villagers that the trader has arrived would be incredibly useful for traders, and will make sure that if someone is online in the village, the trader will be able to contact him even if that person is not on IRC. Give the ring a 30 second cooldown to avoid ringspam, and there you go.
3) Claimble cart.
Another problem with trading with villages we currently have is that you cant abandon or unload your cart inside of village's area. Do it, and you will have to leave a theft scent, assuming you have the theft skill at all. Having a claimable cart, which would be exempt from claim/village territory rules would be necessary to trade inside village's territory and allow villages to have trade depots inside their territory. Though you would probably have to make it more of a large mobile container than a regular cart which can store liftable objects.
Of course, perfectly there would also be a standard MMO trade interface where you could select which items to trade and have a confirm button, but even without these, i dont consider scamming a real problem. There's no reason for trader not to trust villagers, because if they scam him, he can easily report it somewhere (like on this forum), ruining that village's reputation, meaning that other peddlers will less likely visit the village again. And nobody wants that.
A career of a peddler, roaming from town to town, trading goods, traveling the land is something i would really love to try out in H&H, so i hope the post will help the devs make up their mind on how it should be.
