This would make an interesting RTS. 2 teams, 4 players on each side. Each economy can survive on their own, but there is a natural chain that can be built to allow one player on each side to have an overwhelming advantage over the other team (think "tip of the spear"). Only by carefully coordinating resources can you get this to work - the same costs in the beer game apply here (making too much of the upstream resource (inventory) has an opportunity cost in you not being able to produce your own units, and not making enough of the upstream resource (backlog) results in poor teamwork and and having the other team eventually out-pace you. Co-op RTS games sometimes have resource sharing, but I don't think I've ever seen one with a legitimate supply chain (maybe because it ends up being so difficult to coordinate).
