I guess I've never picked up the useless items and don't have the inventory burdens that others do. I thought the useless items did play a role in
the arcane tower quest where the useless items were really illusions.
And I like seeing that one place has glass goblets, another pewter another wood. Makes it see alive. More useless items please! (I'm being totally serious).
But I would like an official poll of the forum. @tuco makes a good point that those willing to dive into the details should be polled first.
