Sure being able to buy new accessories for things like ties would be great, but I would also like to be able to pick up objects that I find on my travels and carry them with me for the session.
I personally would love to be able to pick up a large stick from a forest and carry it with me as I go. I would even do missions with this stick, I would trust this stick.
I sometimes catch myself thinking other players would look great in a shootout if they had a handbag on their side as well. Just my thoughts.
