congrats Joe.
Focus on getting as many citizens as possible. I was slow to do that on my first island, But I've been pumping wine into my second colony and I've almost came up with the same amount of citizens even though the first colony is at least 3 weeks older. More citizens= more luxury and building materials=more money.
Try to keep your town wall and town hall equal... I've failed to do that but I'm working on bringing it up.
