I retired yesterday! I started on the easiest level, but worked my way through the top (always promote), to go one level down to rogue. I had all my family, got the nasty Marquis (rather soon), got married, got 23/24 wealth, all pirates, all pirate treasures and 1 lost city (and one more on the map (4/4), but wasn't bothered to sail there). Is it worth to go on? Finding a lost city is rather boring, when compared to finding the Marquis. Another Q: Is there a way to speed up land battles?
