There are a lot of board games about buying and selling in a market. It's a very popular drama, and having played more than a few I can tell you it's actually very fun. Especially when you have a really cleaver premise combined with great art and solid mechanics. Ecavation Earth lets you play as an alien archaeologist scowerinng the ruins of humanity on an abandoned earth looking for cool stuff to sell or put in meusemums. It's full of helarious little easter eggs,but more importantly it's a very fun well designed euro.
