I was "curious" as to HOW and go abouts creating ONE for this? Whom else CAN'do' likewise? Using the BASIC 'components' and DEVISE some other manner in which to MAKE a "Scenario" for "Sahara"!
I was thinking maybe to put the Supply Cards off to one side as a separate deck, and make some conditions for when a player gets to draw from the Supply Deck... first one to an oasis maybe? Perhaps make it necessary for a player to keep a supply chain from their Depo to use a Supply Card? In other words, new units would be placed anywhere where a line of supply can be traced back to the Depo?
