Armed to the teeth, a ferocious bunch of pirates is descending the river, directly threatening your harbors. How will your Merchant Dwarves fare against the sea rats? Maybe you should have left before, as the Elves did… they told you that they had foreseen great trouble in the Temple of the Seer, but as usual, you didn’t listen. After the pirates, who knows what could happen?

With River World, discover new Small World maps and new places and enemies! Control harbors to score more victory points, use the caravel to reach the far end of the board, or use the temple of the seer to see the future… Each turn, a special Event occurs: pirates, storms, freezing cold – it is not that easy to live in River World.

-note: a copy of Smallworld is required to play
