Alhambra: The Treasure Chamber

Nice little expansion to the game adding instant depth

Great for two players.

I'd play this for variety, but it adds length without adding depth. You're still at the mercy of the currencies available and what tiles come out where. Adding new market tiles requiring exact money simply exacerbates it, locking you even more into the luck cycle. But the added decisions on when to go for markets and the colour targetting for treasures add good variety when tired of the vanilla game.
