NPC - Non Playable Customers is a reversal on the RPG genre.
Now you are the NPC Shopkeeper, who Players are coming to sell their random monster and dungeon loot to.
In NPC, you can craft from of the items you're sold,
to meet the requests of all the Players turning up at your door asking for weapons, and earn some money.
You can craft three types of weapons, with several stats based on what you use to craft it,
to meet their various requests (though some Players are more picky than others).
Go forth, and craft some truly awful and strange weapons,
and perhaps one day you can save up the 94 coins to go to RPG College and quit this lousy slime-buying sword-smelting job at last.
