hi thanks for the review!
The rumor mechanic is still very rudimentary. Currently you „talk“ to the islanders about a rumor, and that spawns a treasure chest in a random spot on the map an shows you the direction via an arrow. In the future this could be expanded to for example a rumor about a big spanisch treasure fleet arriving. Which you than could decide to attack before they leave the playing field. Or maybe there is a rumor about some pirate treasure stored on one of those small lonely islands. Or some shipwrecked people which you can save. All sort of tiny quests could be started this way. But without much time, it is currently very basic :)
