Anno 1700 is an ambitious and sprawled-out pirate game involving two timelines, multiple NPCs, and a large map.
As is often the case with Adrift games, the game works well with the walkthrough but has trouble for someone without it. Very specific actions need to be guessed, and actions that seem like they would be easy (such as communicating with your base) cause trouble.
Playing this with the walkthrough, though, was enjoyable.
Edit: Several people pointed out to me that this was written in Adrift, not Quest, and I apologize for the mistake!
