I have an idea how vendors could work easily in Oort.
To Get a Vendor
First of all, players can receive a “vendor coin” from the capitol of there server (a vendor vendor if you would). These coins are the blocks for placing that vendor and they would come in a variety of types such as food merchant, weapons merchant, armor, tools, mounts, pets, and so on… These types would be priced by rarity.
From here you can place the vendor into your beaconed space and this vendor cannot be killed, but can be moved like any block.
How the Vendor Works
All vendors will begin with a limited starting items. For this example I am going to pick on a “Bread Merchant”.
After placing your bread merchant, it will start by only selling tier one basic bread and will not sell anything higher until a number of tier two items have been sold by players to the shop.
After receiving enough tier two items, lets say 100 sold by players, the vendor will now sell tier two fruit bread. Then after being sold 100 tier three items, the vendor will sell tier three cakes, and so on and so forth.
Through this system of building up tiers, the players more or less control how good the vendor is by their levels and hard work. Also this will allow vendors to more or less level with the success of the area or guild they represent. So more dedicated players will have better vendors.
Mounts and Pets
These vendors will start with nothing, but will work more on an achievement system of gathering particular items. For example, for a plain horse the vendor will have to be sold 1000 carrots, but for an armored horse the vendor must be sold 2000 carrots and 3000 pumpkins. This can also help to promote farming.
For the pets, the vendor may need special items such as a “Gemmed Collar” found only on a particular titan, or some other specialty item that will “unlock” their wares.
Other Specialty Items
As players and their vendors level up in tiers, there will be a call for specialty items, weapons, armors, potions, and enchantments. Similar to the pet system I mentioned above, these vendors will require special items to unlock these rare treasures. And of course they will still be very expensive even after being unlocked.
Who can buy from a vendor?
Anyone, but there will be limitations placed on players by there rank in tiers. For example, a new player can not buy a tier ten weapon. For this, I propose that players can only buy items within their tier or just one tier above them, but that is all.
Also, there should be special discounts to those who are part of the beaconed zone, most likely a guild, to promote advancing their zones.
In Summary
Having a vendor system like this would be a great way to promote players banning together for a cause. Also, this will allow for different forms of play from those who like titan hunting and finding rare items to those players who are more relaxed and just want to farm carrots.
Then with vendors being able to “level-up,” this will ensure that higher level players can challenge themselves and have decent quality armor, weapons, food, and potion for those challenges.
With mounts and pets, this will be more or less a way for players to “show-off” the achievements they have accomplished.
