Yarrr should be in the dictionary. If you were to look up Yarrr in the dictionary, the definition would likely be: “What a pirate says, dummy.”
Anyway, there are plenty of pirates in Risen 2, nothing but pirates in fact.
Risen 2 will be out in Q1 2012. It will have personal ships, killer parrots, wenches, whores and the console version hopefully won’t suck this time.
