Seems like there could be some sort of game using the odd junk loot, such as a black rose, that you can sell to a merchant, but it can't be put on the broker. Not sure exactly how the game would work. One idea is the have it like a collection quest. Anyone else have an idea of some kind of game you play with the concept? I have tried run a scavenger hunt with a list of items before, but since people couldn't buy it from the broker not many people wanted to play. People might play if there was a time limited scavenger hunt from Daybreak and they gave cool stuff for it.
Here are the bank-bags of one of my twinks, full with the junk and treasure-loot. I collected the items over years because of the nice icons and item-texts which could be used as ideas for own rpg stories. This items have an own worth/value for me and I appreciate them very much as lore-resources.
