Over at Tobold’s place. Check it out.
If I can recommend a mini-game variant from A Tale in the Desert: actually craft the item. If you are a blacksmith, you get a blob of metal and a hammer. Go nuts. Some players worked out how to make pretty good shovel heads in 10 seconds or less; other people specialized in getting that last bit of quality out of tapping the metal into just the right shape. You could determine the output by the final shape created or have a set “perfect shape” for a pre-picked output and determine item quality by its similarity to that Platonic ideal.
