Merchants Cove: The Secret Stash

The base game is enough fun as it is, but the Secret Stash adds that little extra that kicks this game up a hefty notch. I love the addition of larger and smaller ships. Adding the 2 costumer ship really ramps up the scores too; my gf and I both scored beyond 300 with both 5 customer ships and the 2 customer one.
The mini expansions are fun too, the halls of plenty and lair of villainy (faction halls) give some incentive t specialize with a certain faction, and the faction leaders can amplify that effect or just be a fun way of essentially adding 4 more customers to the game since they count as double.
My favorite additions to this expansion though are the extra rogue and townsfolk cards. The extra townsfolk just add some fun extra things to do when hiring, I especially like the officials and the artisans. The extra rogue cards are good fun, giving each game a slightly different feel. Their effects vary widely as well, so that you may even pick a rogue that best fits the playstyle of your group, whether you are more of a relaxed and friendly group or a more cut-throat one.
For the price, this is a must have expansion.
