Ni No Kuni 2: Revenant Kingdom is an ambitious games with some very different components. First and foremost, it's a somewhat traditional RPG, although it more heavily emphasizes real-time combat than its predecessor. The game also features some real-time strategy elements and, somewhat in the vein of classic Suikoden games, the ability to manage your kingdom.
You'll initially start out with a small castle, but over time, your land expands and will become home to numerous characters and buildings. There are aspects of this which involve managing resources and dealing with cooldown timers, while completing certain side quests allows you to recruit new citizens. Although the game doesn't force too much of this upon you, there are certain points in the story that do require your kingdom to meet certain thresholds.
In the video above, we run through some tips on how to best manage the various elements of your empire. One useful, if obvious, piece of advice is to check in routinely--you can collect money and supplies that accumulate, but there is a cap; don't check in often enough, and the excess will go to waste. On a similar note, expanding your coffers will give you some additional wiggle room before your kingdom's gold stockpile hits the cap.
We also go through the different types of buildings and the benefits that each provides (such as increasing your Influence, allowing you to expand your kingdom, construct new buildings, and so on). You'll get a sense for all the basics that you need in order to succeed.
