Anno 1701 is the first one with free camera rotation in all dimensions. You could zoom in and admire your city up close. And there's something to look at as citizens roaming the streets. This is also the first instalment with neutral quests that help you get resources and gold. And now for the strategy that's the best for almost all Anno games - always set taxes to the highest possible level without damaging your economy. Only lower them when you need something from your citizens - upgrade to the next level or grow. Once you satisfied with the result, crank those taxes back up and get heaps of gold. Good luck, settlers!
