We played Cargo Noir last night for the first time and we found that by the end of the game, half the cargos in the black market had been there from the start.
When you are at Macao, you can swap or pick a random cargo from the bag.
Since you need to have a cargo to swap for a cargo, players often chose to random pick out of the bag as it increases your cargo and still carries a chance of getting what you need.
This meant that people tended to ignore swaps and go for random in every stage of the game, and the market became stagnant.
Are there any suggestions on ways that increase the turn over of cargo on the market and freshen things up?
