I sure wish there were more than just 3 guild quests in this game. Because no matter what anyone says, there are 3.
There the one where I have to do The Island of the Pirates and pay a random resources. And this one occurs every other time. In between The Island of the Pirates, I either have to do The Dark Priests and pay a random resource or make 25 settlers and pay a random resource. I have 4 explorers, and if I send them out on short adventure runs every time I can, I might just get myself one Island of the Pirates every 10-15 days. But I'll have had to buy at least 5 in between, because that one comes up every other time.
It would sure be nice to see an entirely different concept on guild quests.
