We only have a limited number of inventory space, but a-lot of items we want to keep on us. Now, we did just get more space added to our inventory, but that wont help us long term. What if there was a banking system, that if you bought a vault you could store items and money in for ___ amount per day/week/month/whatever. For example, lets say you got a couple hats that you like and want to keep, but don't want to have in your inventory because it takes up a-lot of space, With a banking system you would be able to store those hats, for lets say 1000 per day. That way you get to keep the hats, and get your inventory space for the cost to make it fair. Of corse the details of this system would be up to you, I just thought this would be a fun and fair way to store large amounts of items.
