It would be cool if:
Zombies killed in Plains drop Hops
Zombies killed in Mountainous drop Iron Scrap
Zombies killed in Swamps drop Glowing Mushrooms (enchanted mushroom, grey or red.) (very rare drop)
Skeletons killed in Swamps drop Flax
Skeletons killed in Snowy drop Gold Teeth
Skeletons killed in Plains drop Torn Chainmail
Spiders killed in etc.
Item Exchange Quests:
Player takes 10 Hops to Brewer-NPC (one of 4?) around the map, to exchange it for Ale (relabeled brown potion?)
Player takes 10 / 100 Iron Scrap to Architect-NPC (one at spawn, one in hell) to exchange it for Building Permit / ??? (respectively)
Player takes 10 Glowing Mushrooms to Druglord-NPC (hidden at spawn) to exchange it for Herocrack
Player takes 10 Flax to Bowry-NPC (one of each race?) around the map, to exchange it for Reinforcements
Player takes 10 Gold Teeth to Bounty-NPC to exchange for an Award.
Player takes 10 Item to NPC to exchange for an Award.
Additional Requirements/Information:
10-100 Ale could be a township requirement and upgrade fee.
10-100 Building Permits could be a township requirement and upgrade fee.
5 Herocrack could be a Hamlet start up fee.
Township fees.
Township upgrade fees.
Kingdom taxes.
Monetary rewards.
Stackable slips exchangeable for currency or unique items/services. (NPC enchanting, smithing, and building blocks such as smooth stoneslab as a solid block.)
This would add some form of a unique economy that could be used by players to acquire goods through manual labor outside mob hunting around their township.
They'd be forced to find NPC's who want the items they get, and exchange them for a reward. Some items could be accepted by multiple NPC's.
The command for the NPC to buy it could be simplified.
"Buy my Iron Scrap 5"
-If in range of an NPC will prompt it.
"Sorry! I don't buy those!"
-Nothing happens.
"I will give you 50 Coins for that."
-You receive 50 Coins via Economy plugin.
(There doesn't need to be an additional check to see what you get for the item. That can be explained with a sign beside the NPC or in it's building.)
IOW: no need to program
"What is Iron Scrap 5 worth?"
-Nothing happens.
"I buy Iron Scrap for 10 coins each"
-Nothing happens.
This could be done with a Graphical user interface perhaps, if you could click things in a book that could issue commands like these. (Hopefully not abusable.)
Anyway, just a random thought I had.. and it would give the quest and lore team a basic direction to go in regards to what the scope is of the NPC's they're looking to have placed around the map.
PS.
I don't even know if this is possible.
