I totally agree. Okay it's a prison and we shouldn't be swimming in loot and especially magic items. Okay some of the stuff is low quality and shouldn't sell for much. But right now equipment overall sells for far too little. Even magic items and unique items sell for very little.

I think that The prison economy needs to be rebalanced. Right now the most valuable things you can sell in the prison are the gigantic, heavy paintings, and those are exactly the sort of things which no one on the island should be interested in buying.

What should be in demand and worth lots are food, water, medicine, weapons, equipment. Maybe some small valuables. But not paintings.

What's worse is that the few times I have found skillbooks in random loot they've all been duplicates.
