Each asset will have a space value that is used to automatically calculate how much stuff can be carried by a person, barge, boat, etc. or stored at the base camp or town hall.
Assets distributed by the game will be limited in number. Crafted items will not be limited, the economy will keep these under control.
For example, a Basic Hut will take up 250 squares. The Basic Hut is tokenized, but can be upgraded to a larger structure in order to store more inventory. When you upgrade a structure, you will be issued the next level token and may sell your old token to a new player.
Some salvaged items are repairable and require other salvaged items to repair. This is where professions and hobbies come into play.
Common items are repairable by anyone, however, hard to find and rare items are only repairable by specific professions. Anyone may buy, sell or trade any item.
